In the 1950's, the primary uses of the word "bugged" was to describe a room that contained a hidden microphone, or to refer to a telephone line that was being tapped.

Over the last few years, I've seen more and more people use the word "bugged" to refer to a software bug.

For example, someone recently wrote, "That function returns the wrong value, it is bugged."

In contrast, I am used to people writing, "That function returns the wrong value, it has a bug."

Is the use of the word "bugged" to refer to software bugs now universally understood in the English language, or is it predominately used in specific regions?

As a bonus, does anyone know where this particular use of the word "bugged" (as opposed to "bug" or "buggy") originated, and when. Also, was the origin fostered by a specific cultural group?


The number of programmers with decades of experience stating they have never encountered anyone using "bugged" in this context is notable. I postulate that this effect is a consequence of people largely being exposed to highly monolithic environments. For the non-programmers who state they have never heard people using "bugged" in this way, that is possibly just a reflection of their limited exposure to technical content, as every time I have seen it used has been in a technical context.

For any doubters, programmers or otherwise, here are just a few concrete examples from the real world:

For those interested, general web searches provide thousands of additional examples. Searches directly on technical websites provides many more examples.

(Note that the above are random examples pulled from a web searches. I apologize in advance if there is any inappropriate content. Many thanks to NVZ for making the list of examples easier to read.)

    In 40+ years of writing software I have never heard someone say that a program is "bugged" if it has a defect. "Buggy" - yes. "Has bugs" - yes. "Bugged" - never. May 21, 2016 at 16:11

    Given that this use of "bugged" is undeniably in use within software development circles, I updated the title to make it more clear. I personally find this use currently sounds weird, but then again, sometimes things sound weird before they become normal. Almost every sentence on this site would sound weird if read 150 years ago. Expanded to a larger scope, the notion of equal rights for all people likely sounded preposterous to many people not long ago, and still sounds preposterous to some people today.

    As a millenial programmer, I can confidently say that I've literally never heard the term "bugged". I'd also like to note that (1) it's highly unlikely that multiple people who've never heard the term have all worked in the same "monolithic environment" and (2) any English phrase which "can" be used to describe something probably has been used in every fashion possible, including in the question being asked here - that doesn't mean it's predominant, common, recognizable, or even appropriate for the context.

Before there were software bugs and software programs that needed to be de-bugged, the term existed and applied to defects or flaws in circuits, machines or operations.

From the Index to Radio for the Year 1937:

There can be no doubt but that many new and simple noise silencers will appear, both of the amplitude limiting and the "silence punch" types. Several are known to be in the laboratory and they should be "de-bugged" before long.

From 1951, The Flying Lady

An ignition system, no matter how ornery, is still logical, and can be de-bugged using step-by-step analysis

From 1959, Automatic Control:

two members of the class trying to repair one of the twelve Dynalog recorders which were purposely “bugged” by the instructor

From 1960, from an article about the "IBM Development Laboaratory in Endicott, New York" in Missile Design & Development volume 6:

At the conclusion of this study, 2500 randomly inserted bugged components had been investigated. An automatic detection capability of 99.1 percent was attained for a group of 300 consecutive tests. An average of two package replacements were required in this study to correct any of the bugs introduced into the machine.

From 1960, Radio-electronics, Volume 31 :

It is very likely that the tubes that give unsatisfactory oscillation are being “bugged” by parasitic oscillation.

Then the word "bugged", already in use, entered use in software:

From 1962, Fundamentals of electronic data processing: An Introduction to Computer Programming

We are going to assume that this programmer knows no more about his job than you would, at this stage. In fact, we are going to assume that you are this programmer. A "premature" programmer.You will produce a program bugged with wrong assumptions and errors, so that it will take several tries before you develop one that is workable.

From 1964, by Micheal J. Synge of Boeing, A Case of Too Much Precision, Communications of the ACM: Volume 7, page 723 :

...I have transliterated it into FORTRAN II for the IBM 7094. In doing this I stumbled across solutions to a decimal-to-binary conversion problem that has long bugged FORTRAN.

Thus only bugs capable of yielding this result need to be considered....For reasons of tractability and clarity, we also stipulate that the bugged code may only have one difference from the ideal code, that of the bug chosen. ... If the 'problem' clause has a lower number than the 'ideal' clause the traces will show a failed resolution for the 'ideal' code where the 'bugged' code has a successful one.

The execution of this bugged version starts with an initial state where N=4, and terminates with a segmentation fault.

From 1995, The Mathematica Journal:

This article discusses the advantages of a general method, called distribution-free testing, and demonstrates it at work correcting a very badly bugged multiplication function...Coping with such a bad function should therefore be an interesting challenge for distribution-free testing.

These numbers were due to a bugged implementation.

From 2013, Software Design for Real-time Systems:

So "de-bugged" and to a lesser extent "bugged" have been used as long as there have been software bugs.

So the answer to when is between 1959 and 1965.

As to, where, well Professor Dreyfus was at MIT when he wrote Alchemy and Artificial Intelligence in 1965, which includes "bugged program".

The prevalent usage is "the function has a bug" or "the function is buggy".

There is a very subtle, but important difference that is highlighted when you look at the word debugging. Debugging is the process of intentionally tracking down and removing bugs. Bugging would be the opposite, intentionally placing bugs.

This makes sense - if a room is bugged, then a person purposely planted a bug there. But for software, this would mean someone purposefully wrote those bugs into it. This might happen, but is unlikely (e.g. a hiring test where you are tasked to debug something that has ben bugged on purpose before).

So if you say "the function is buggy", you simply describe the status quo - without giving an assumption about how it got that way.

At least, that is what the current, prevalent usage amongst people more involved with software is. But bugged seems to be becoming more popular especially amongst young, inexperienced people new to the field.


While I agree with others that 'buggy' is far more common usage, I do hear the term 'bugged' used to describe code from time to time. Additionally, it is usually from professional software engineers or developers who are native speakers of American English that I hear the term used.

Usually, I hear 'bugged' in reference to code that has (or had) a particular, known bug. For example, it could be used as:

We're aware of that behavior. Version 1.0.2 was bugged, but this was corrected in 1.0.3.

Of course, the phrase "had a bug" could have been used equally well in that context.

'Buggy,' on the other hand, seems to be a broader term that can describe software that has a particular, known bug, software that is generally of low quality, or software that is not behaving as intended for a reason that is not yet diagnosed (or some combination thereof.)

In the example I gave previously, I would personally prefer "had a bug" or 'bugged' there rather than 'buggy,' because saying

Version 1.0.2 was buggy.

sounds like

Version 1.0.2 was full of bugs.

rather than

Version 1.0.2 had one particular bug that we know about and have since fixed.

  • I'd prefer to specify which bug. I agree that "buggy" is indicative of a wider problem; I suspect it's used mostly for software that either glitchy (intermittently faulty) or has a number of non-blocking bugs (which affect some functionality, but wouldn't necessary prevent the product from shipping).

At the moment, this seems like a common mistake rather than a new usage. I think it's a logical guess to use 'bugged' that way' like using 'breaked' instead of 'broken.'

However, when native speakers and domain experts all use 'buggy', and 'bugged' is often found in sentences and paragraphs with basic errors, it suggests a mistake rather than a new usage.

For example, we see it in paragraphs like this:

This Tool is only usable by EVE Online Gamer. The tab source code does not hold the source caus this is pretty bugged for me, use the zip in download instead.

But you never see it in professionally written books or hear amongst native-English-speaking software developers.

If 'bugged' were usable like this, it would be because it was the past participle of a verb, 'to bug,' with the meaning of 'to add a defect to software.' This would make the following sentences seem natural;

the programmer bugged the function


I keep fixing it, and he keeps bugging it again.

It's not, therefore, a valid sense of 'to bug,' which only means 'to install a monitoring device' or 'to annoy'

    But then you're begging the question (in the proper rhetorical sense); the argument is circular.

I often hear bugged used to mean that something is in a non functional state. It's more often used to describe that something is currently broken, either completely or partially. Typically I hear it used when talking about some feature or component as a whole, rather than talking about specific code.

For example, it is common in gaming communities to refer to a mission/quest as bugged if it is not functioning properly. A quick search for "bugged" on World of Warcraft's forums returns 37,100 hits and for Hearthstone's forums 4,660 hits.

I would certainly say that using bugged to refer to a software bug is becoming commonplace.

  • We used to use broken for something that's significantly, well, broken. I'm thinking about developer/tester usage, though. I'm not sure where gamerspeak is at these days.

    WoW was also where I've seen/heard "bugged" the most. Gamers are much more likely than most non-developers to talk to each other about software bugs. "bugged" is a binary condition, though. If something sort of works, or only occasionally breaks, people that would say "bugged" instead of broken will still say "a bit buggy" instead of "a bit bugged". May 17, 2016 at 7:00

    WoW and Hearthstone are probably the best sources for non-English language speakers talking about software in English. I would expect the highest levels of mistakes in their use of the language, so am not surprised to hear this confirmed. May 17, 2016 at 15:13

The following Ngram confirms the many answers that "buggy" is the conventional term in the context of software, whereas "software is bugged" and "code is bugged" doesn't feature at all in the database used by Ngram.


Here are some definitions:

Buggy adjective - of a computer program, system, etc. : having many problems or errors that prevent proper operation : having many bugs - M-W

(definition 3) 1. transitive verb : to plant a concealed microphone in
(definition 3) 2. transitive verb : bother, annoy don't bug me with petty details
(definition 3) intransitive verb : to lose one's composure : freak —often used with out
(definition 4 - of the eyes) intransitive verb : protrude, bulge —often used with out
(definition 4 - of the eyes) transitive verb : to cause to bug
- M-W

Buggy code describes an attribute of the code itself, while bugged code refers to something done to the code.

Based on the definitions, Ngram and personal and others' experience, "bugged code" is not idiomatic when referring to code with software problems. The term is likely a back-formation from "debugged".

    @DavePhD The OP cites many more examples of the use of "bugged" for "buggy". However, "bugged" in this context is not idiomatic and arguably not fluent. I'd grant that it may be a back-formation from "debugged" so there is a plausible argument for new usage, though whether this is becoming mainstream will need to be established via more recent corpora. My primary argument here is that it's not the case in my experience and the collective experience of the other respondents, for good reasons backed by established differences in the ways the verb and the adjective are used.

I've been doing software for a few decades now and have never heard "bugged" to describe code with faults.

For native English speakers "bugged" already has two common uses: 1) meaning something or someone is annoying the speaker or 2) a covert listening device.

The word "buggy" and the phrase "to get the bugs out" or more revealing "to iron the bugs out," comes from the pre-pesticide days when lice were common. Has lice and lice eggs could survive a standard washing of the era, the only way to remove them clothes was to go over the clothes with a hot iron. It's also why having freshly ironed clothes became a status symbol. If you had a rumpled look, you might have lice as well, and be buggy. But no one would have said you were "bugged."

The terms transition to computer famously occurred in WWII when then Lt. but eventually Vice Admiral Grace M. Hopper, traced a fault to moth beaten to death in one of the electro-mechanical relays of the system she was programming (don't remember which one at the moment) using the sense of bug and buggy from the previous paragraph, she logged the episodes as IIRC, "I got the bug out," and from then on bug, bugs and buggy became programmer speak for a fault.

Sense "bugged" doesn't have the same connotation as "buggy" historically I'm going to say it's never really been standard usage. Probably seen most often as the result of editors trying to eliminate passive voice.

Of course, the term could be evolving. It might be "Buffy-Speak." My favorite example being, "Could you vague that up a little more for me?" Turning "vague" from an adjective to a verb.

  • 2
    While I agree with all your main points, as an aside, the famous Grace Hopper anecdote actually reveals that the usage of 'bug' was prevalent before the moth episode - the joke was that it was a 'bug' in both senses.

    As a counter-point to your anecdotal evidence, I have also been a software developer for a decade or so, and I have heard "bugged" a bit; it sounds natural to me to say "this function is bugged in version x.y.z".

    Plenty of real-world examples exist. It's not as common as "buggy" but it is by no means rare or unusual. In fact, I heard it used by a .NET developer earlier today when he said that a service was bugged.

The only time I hear "bugged" used around software is when used as "DEbugged". For example, "She debugged my code."

Code may be "buggy", not "bugged". Code may be "debugged", not "bugged". Code is never "bugged". Don't say that that. It's weird. Any examples to the contrary are examples of people doing it wrong. Tell them to stop. Don't follow their example. Shame them.

    Wow, that's an awfully rigid stance. May 18, 2016 at 21:53
  • And DavePhD gives examples to the contrary going waaaay back to present day... I would offer though that the usage never really caught on in the first place and still hangs on like the vestigial wings on an Ostrich. ;) May 19, 2016 at 22:37
  • @TracyCramer LOL. That's definitely one possibility, although I'm seeing it's use by many young people, so it's more like a new genetic mutation in which the ostrich has grown a third leg. The benefit is that they are setting new land speed records. ;) May 20, 2016 at 0:17
  • LOL - Now THAT'S funny ;) May 20, 2016 at 16:05
  • @RockPaperLizard - he is merely holding you to a standard he maintains consistently. Software developers have to achieve perfection in spelling, punctuation and grammar before our code will compile. When we not only can achieve perfection but are obliged to do so all day, every day, why should we tolerate sloppiness, laziness and ignorance in others?

There are lots of great answers here! I think Nicholas is on to something when he mentions use of the term by children. I've also noticed "bugged" being used (in the US) to describe buggy software primarily among young (teenage) "gamers", as opposed to software professionals. This may be the beginnings of a transition in usage... Not too long ago I'd have said something "has a glitch", but not that it's "glitchy" or "glitching". All three sound fine to me now, though I'll admit that it's going to take a while for "bugged" to sound right (and not conjure mental images of wiretapping).

    I'm a 30-something professional developer that uses the term. Maybe I'm just really "down with the kids".

The term for software with faults is at the boundary between the specialized language used by software developers and the language used by everyone. Laymen and laywomen talk about bugs in software.

Software developers will call a single software fault a "bug", software that doesn't have such faults "bug free" (although that happens only very rarely), software that has too many faults "buggy", the process of removing bugs "debugging".

Non-software developers may call software with bugs whatever they like, for example "bugged". Software developers hearing this just cringe and don't change how they call it. No doubt that you can find examples in the literature, but very few from software developers.

  • I think you raise a very important point. While the meaning of professional jargon may evolve within a profession, lay opinion on the meaning of the word is irrelevant.

    @PeterWone You may have that backwards. Colloquial usage of words often dictates the more prevalent use, even if that meaning is erroneous. For example, the consistent colloquial erroneous use of the professional psychiatric terms schizophrenia and OCD by lay people cannot be described as irrelevant. In those cases, the lay opinion has been so strong that most non-experts (and many experts) no longer understand the true meanings of those technical terms. But in this question, we are referring to a word that is being used with a different syntax, not a different meaning. May 21, 2016 at 21:01

In the fine tradition of verbing nouns, software can "bug out". Naturally, the past tense of using "bug" as a verb, is "bugged".

Software bugs out, or bugs up a process. I don't hear the term very often, but I have come across it. I've typically felt that such usage was rather informal. The word, used as a verb, simply means to experience/demonstrate a bug.

"Ah! It bugged me!"

(Actually, that would be very straightforward English, using the word "bug" like "irritate". However, it could also be used like Nickelodeon Slime, when children on TV would slime their parents, which meant dumping slime on their heads.)

I have also heard "buggered", though also very uncommonly (and I would be even less inclined to use that word in communications where I was striving to be formal).

In general, I would consider such usage to be rather informal (as already mentioned twice), and possibly even improper, but generally understandable. Such is how I've seen several words evolve. I would expect this usage to become more widely used, and more widely spread, if computer programming skills grow among the general population. Until then, I suspect that other ways (to phrase the concept) will likely be more widely appreciated.

  • "buggered" means something totally different. It can be used the same as "f***** up" for software that has too many bugs, but that the first few letters coincide with "bug" or "bugged" is probably coincidence.

  • "Don't bug me" might be something you tell a six year old when he asks for ice cream for the third time after being told "no" twice already. Also unrelated to software problems. Of course software bugs can be annoying, so I might say "this bug is bugging me" (I probably wouldn't) meaning "I find this software fault very annoying".
