The OED gives ‘username’ and has three citations, from 1971, 1997 and 2007, in support.


In English, there are three types of compound words: the closed form, in which the words are melded together, such as firefly, secondhand, softball, childlike, crosstown, redhead, keyboard, makeup, notebook; the hyphenated form, such as daughter-in-law, master-at-arms, over-the-counter, six-pack, six-year-old, mass-produced; and the open form, such ...


When contrasting with "necessity", Doug's option is a typical contrast. Maintenance shouldn't be an option, but an all-important necessity. Another contrast tends to be luxury. Maintenance shouldn't be a luxury, but an all-important necessity.


The correct spelling in this case is username. The username is the (usually unique) thing you type in with your password, for example: bobsmith66. The user name is the name of the user, the user's real life name, for example: Bob Smith. User name is sometimes used for username, but occasionally it makes a difference, so be clear and avoid the ambiguity. (...


I would argue that the 'State of the Union' is an address to the nation, and therefore the plural of State of the Union Address is 'State of the Union Addresses' since "State of the Union" is modifying the word Address.


For the compound noun front + end it is front end: Noun front end (plural front ends) (computing) that part of a hardware or software system that is closest to the user. frontend and front-end are alternative forms. The compound noun front + end + engineering may be another matter.


Bonus carries the non-essential nature of what you're after. Maybe "bonus feature", or "added bonus".


Surprisingly, some dictionaries such as Collins and Dictionary.com do list sightsee as a verb, with sightsaw as the past form. On the other hand, I have never heard anybody actually say it. I have heard plenty of people say went sightseeing. A quick trip to Ngram to compare the usage of sightsaw against went sightseeing comes up with plenty of instances of ...


Obligatory Google Ngram: In case the link breaks again: username is much more common these days; user-name is not used at all.


nicety [nahy-si-tee] –dictionary.com Usually, niceties. a refined, elegant, or choice feature, as of manner or living: working hard to acquire the niceties of life. Maintenance is not a nicety, it's an all-important necessity.


"Frontend" and "backend" in this situation are technical terms, and as such I don't think they conform strictly to traditional ways of creating new words. I'd put it in a similar category as putting the letter "e" in front of things: For example, should we call it e-mail and e-commerce or email and ecommerce? Most of us have settled on "email" but we split ...


It should be two words: "First Name" There does appear to be an upward trend of lumping the words together, but it's still pretty small - and incorrect. I suspect some factors in that trend include: Popularity of "username" leading people to think that all such uses can be smushed together into one word. Accidental or automated use of naming conventions ...


According to the Oxford English Dictionary, as quoted by the site below, you hyphenate if the compound adjective is before the noun and don't hyphenate if it is after the noun. With compound adjectives formed from the adverb well and a participle (e.g., well-known), or from a phrase (e.g., up-to-date), you should use a hyphen (or hyphens) when the ...


The difference between "real time" and "real-time" is mostly a matter of style and placement. In most cases, there's no need to add the hyphen; "real time" will work very well. However, a case can be made for its use where it would clarify the writing. For example: I am updating this in real time. or This is a real-time update. In the second ...


I've seen both "username" and "user name" used widely. Both are acceptable. As far as I know, techies mostly prefer "username". "User-name" just seems awkward.


This is complicated, because "State-of-the-Union" is being used as a noun when it isn't really one. If "State-of-the" was being used to describe a Union, then Union would be pluralised to Unions If "of-the-Union" was being used to describe a State, then State would be pluralised to States. But "State-of-the-Union" is an abbreviation of "State-of-the-Union ...


"State-of-the-unions" is entirely appropriate in informal spoken English. The context you give is quoted speech, so I would say it is fine. In fact, the utterance would have less force if any other option were chosen.


I like the spelling convention set in GCC Coding Convention: "front end" (noun) "front-end" (adjective)


Forward slashes have been around forever (well, at least since Ancient Rome), but they were just called "slash". Backslashes, on the other hand, are a fairly recent invention. How ASCII Got its Backslash reports that it was added to the ASCII character set in 1961 for the Algol programming language. The term rose in popularity in the early 80's, probably ...


Wavelength has been adopted as a term for a dimension (of measurement). The other phrases have their respective terms (wave height: amplitude), as such they are separate individual words.


The construction 'something up' is informal American usage, typically when encouraging, exhorting, or castigating someone. Originally seen in "man up" or "cowboy up" (Free Dictionary), respectively meaning: to adopt a sufficiently resolute approach or course of action to adopt a tough approach or course of action If I say to someone: You need to ...


Great question! Save for the oral echo, there's no necessary relationship between gerontology and ontology. The t comes from the genitive case. Here is the Ancient Greek Wiktionary entry for γέρων (geron). Note that, unlike English, Greek has several noun cases, including the genitive γέροντος (gerontos), the dative γέροντῐ (geronti), and the accusative ...


The stem of the Greek noun erôs "love, desire" is normally erôt-, not er-. So it should be erotogenic or erotogenous in English. Cf. phôs, phôt- "light", as in photograph, not *phograph; erotic, not *eric. That said, there are forms in Greek that use erô- and era- as stems, like the verb eraô/erô, "I love". It's just that er(a)- is the ultimate root of all ...


You're looking for "States of the Union". "State of the Unions" would imply that Trump is giving one speech about many different Unions. This rule also applies for mother-in-law (=> mothers-in-law) and commander in chief (=> commanders in chief). It's explained here: Words that are pluralized in the middle?


One-to-one is used when you talk about transfer or communications. You may use one-to-one when you can identify a source and a destination. For eg., a one-to-one email is one sent from a single person to another, i.e., no ccs or bccs. In maths, a one-to-one mapping maps one element of a set to a unique element in a target set. One-on-one is the correct ...


Maintenance shouldn't be an extra. extra n. an additional feature. {R H K Webster's} extra n Something more than is usual or necessary {AHDEL; same link}


It is a "fish and chip" shop, but you order "fish and chips". Or just a chip shop since they always sell fish too. In general, a shop selling a product refers to its product as a collective noun in the singular. Chip shop — sells chips. Cake shop — sells cakes. Curtain shop — sells curtains.


The reason that wavelength is only one word is that humans commonly form new words by combining existing words together. This is called compounding, and is observed over and over by linguists studying the evolution of languages. The reason that the other terms you mention, “wave height” and “wave speed”, have not compounded is that they are different from “...


Roll back is a standard phrasal verb. Roll is the verb part, and back is the particle. Rollback (stress on first syllable) is an event nominalization from roll back (stress on second). As a phrasal verb, roll back participates in the usual alternation with direct objects: Roll the carpet/budget back. (Vb + Noun DO + Particle -- OK) Roll back the carpet/...
