Okay, so I know when to "but I digress"; I use it when I'm talking about something and then stray off topic and talk about something else, so in order to get back to the topic, I say "but I digress".

But the dictionary says that digress, a verb, means "to stray off of something, to wander from a path, or to turn aside, etc.". So when I say "blah blah blah, but I digress", it's like I'm saying "blah blah blah, but I stray off topic." So when I say that, do I mean:

blah blah blah, but I'm a person that usually goes off topic, so let's get back to the main topic.

Or do I mean:

blah blah blah, but I'm straying off topic, so let's get back to the main topic.

I'm pretty sure this (the second one) is what we mean when we say "but I digress", but shouldn't the correct English be "but I am digressing" or "but I digressed"?

  • so is the phrase "but I digress" or "but I digressed"? and is it used either before and after the person digressed? So if it is before, I think it is "but I digress", and it means, "let's talk about something slightly off-topic here", and if it is after, then it is "but I digressed" and it means "what I said was perhaps related but off-topic (and let's go back to the main topic)." I might have felt that way because it feels like a $2 word instead of common daily expression. But I guess if in some formal speech or lecture, it is more commonly used Commented Sep 15, 2019 at 19:55
  • I was going to ask a similar question today: why is the phrase always in that same form "but I digress", writers seem to go out of their ways sometimes just to fit the "idiom" in that exact form, why not other forms like "sorry for the digression" or "let's not digress", etc Commented Aug 27, 2021 at 15:59

I digress is relatively idiomatic, and thus, even though the present continuous would be normally used, i.e. "I am digressing" it isn't because it's been culturally solidified.

You mean the second sentence. The phrase is indicating self-consciousness of being off-topic, and therefore a return back to the original topic.

  • My understanding was always that "to digress" is to return to an original topic. Rather than acknowledging the deviation in conversation as having digressed, the act of digressing is the opposite... jumping back to the main thread. This came from college professors pre-2000. Did the word flip, or should they not have been teaching? I guess that latin root of "walking aside" answers that they were wrong :)

Digressions used to be a big plus for classical writers. It was considered cool to interrupt a battle scene that mentions a tribe of barbarians and launch off on a thousand lines or so of well styled prose giving a complete history of the tribe from Day 1, or some such. Or to launch off on a critique of one of your sources when referencing him.

These days these are put in footnotes, or even better endnotes to avoid breaking up the narrative flow. Styles have changed.

So the "but I digress" is a notice to the listener or reader that you have done this and are breaking back into the interrupted flow again.


We borrow this phrase from older references, more likely to use the simple present than the progressive one. But there is nothing wrong with saying 'Now I see.' or 'But that stinks!' So there is no problem with 'But I digress.'

It also holds a tone of 'as usual', when you avoid anchoring the present to the progressive form. In this case, I would always say 'But I over-complicate things.' or 'But I criticize too much.', because I am 'copping' to having a habit of the behavior I have just demonstrated.


In speech it can be used in a slightly different way than in literature. However the basic idea is the same. In speech we don't use that phrase to move from point to point. Can't you tell how redundant and possibly annoying that would be if every time we "digressed" from one topic to another we pointed that out. Naturally we assume the listener understands that we have strayed off topic. Therefore it is unnecessary to inform the listener of the original digression. So speakers have created overtime a system of informing the listener that one is returning to the original topic. In a sense this phrase would actually be more accurate if we said "but I have already digressed from the main topic, so I will digress to the original topic." But that's kind of a mouthful.


I am not sure that is it an idiomatic verb, but it is used mainly when someone, on purpose or not, move away from the main subject of a conversation. Is has a negative connotation in that it underlines the fact that you are wasting time not coming to the point in what you are saying. The noun digression has been more used the the verb itself , but its usage has declined trough the years. Rather than 'I am digressing or I digressed' I think it is more likely that the persons that you are talking to will tell you 'stop digressing please, and come to the point of what you are saying'. or we are tired of your digressions

Go off-topic or go back to the main topic are less formal in style Ngram


TS Eliot made "but I digress" a common idiom in the English language, in my opinion. In "The Love Song of J Alfred Prufrock, the poet muses, "Is it perfume from a dress, that makes me so digress?" In fact, the whole poem is one digression after another. Read the poem . . .
