Is the meaning of the phrase "Not for nothing" literal, or idiomatic, and if idiomatic, what does the idiom mean? If you have a reference more reliable than urban dictionary, please share it. Here are two quotes using the phrase in which its meaning seems literal:

Not for nothing had he been exposed to the pitiless struggles for life in the day of his cubhood, when his mother and he, alone and unaided, held their own and survived in the ferocious environment of the Wild.
-Jack London

It is not for nothing you are named Ransom.
-C.S. Lewis

However, this phrase comes up all the time in Aaron Sorkin's writing, especially the TV show The West Wing, and its usage there seems more idiomatic. For example:

Not for nothing, but, you know, we're gonna have to get into the thing at some point.

Josh Lyman: We elect these people. And not for nothing, but if we'd been the world's policeman in the thirties, you and I...
Toby Ziegler: We'd have had a lot more relatives.

In the previous two examples, the sentence structure was

"Not for nothing" <verb> <rest of sentence>

but in the last example, the structure is:

"Not for nothing", <but>, <full sentence>

I suspect that the phrase is being used idiomatically in the last example, but I am unsure of the meaning in this context.


In its straightforward "literal" sense, not for nothing is equivalent to for a very good reason.

But lately in the US it's used idiomatically (often followed by but) defined by UrbanDictionary as...

used to soften the blow of something that would normally be offensive or come on too strong.

There's also this Wordpress post giving the meaning “What I’m about to say is important” - which "sorta" makes sense as a "literal" usage (I have a good reason for saying what I'm about to say), though I must admit I've never come across it. But it can be seen as a "bridge" between the literal sense and the otherwise impenetrable idiomatic usage above (I have to tell you this because it's important that you should know it, but I don't want to tell you, because you won't like hearing it).

  • Though it doesn't seem very logical, I would actually say the meaning is almost the opposite of “I have a good reason for what I'm about to say”—to me, it says more “There's nothing particular that [in what you've just said/the present situation] that's making me say this, but…”, making it clear that this is a statement that comes truly from yourself, not spurred on by—or possibly even related to—anything in the context. – Janus Bahs Jacquet Jul 20 '14 at 11:58

    @Janus: I dunno. I wasn't familiar with OP's usage before this question came up, but this entry on UsingEnglish seems to accurately describe most of the instances I looked at after googling not for nothing but. I wonder if your interpretation arises by conflation with the pragmatic "introduction to topic-switch" that I'd normally use in your context - "Apropos nothing, [some non-sequitur]". – FumbleFingers Jul 20 '14 at 12:43
  • I would use “apropos (of) nothing…” if it was an actual non-sequitur, but “not for nothing” implies that the speaker thinks the point about to be made is both relevant and important to the topic—it's just not directly spurred on by anything in the topic this far. It's kind of a curve-ball. – Janus Bahs Jacquet Jul 20 '14 at 12:47
  • where does this phrase come from? – アレックス Aug 13 '14 at 18:24
  • From Mystic River by Dennis Lehane, “Hey, Kent?” Whitey said, and Kent smiled at him. “I mean, not for nothing, right, but who really gives a f%ck?”. This works real well with the "softening the blow" definition. – dgo Jul 13 '16 at 17:04

"Not for nothing" means, literally, "for something," but should be interpreted as "there is a good reason that..." It is used to describe something fitting.

  • That's only the first of the senses quoted, the literal one. – Janus Bahs Jacquet Jul 20 '14 at 11:54

I have always interpreted hearing this as "Naught for nothing," rather than "Not for nothing."

As mentioned above, I can tell you that is it not for nothing that I am typing this response. But the way that I hear people use this phrase is always followed by a "but" and then some opinion or advice.

So I heard it as "naught," and assumed that it meant "I am offering this opinion, and its value is nothing but you have paid nothing for it." Or, "here is nothing in exchange for nothing." You may also just as easily be saying "I know you didn't ask my opinion, but..." or "What I am about to say has no value, but..."

So, this post is "naught for nothing." You may get nothing from it, but you also didn't ask for it or pay anything for it... its nothing for nothing.

Most people who use it, though, likely just use it as a mix of verbal filler and a clumsy way to qualify their opinions to try to cut off any argument about what they are about to say.

  • Can you find any examples of this usage? It would make a lot of sense – Joe Aug 20 '15 at 19:12

In Dutch there is the saying "Niet voor niets", it means literally the same as the English version. Could it be the case that Dutch native tongues introduced the phrase by mistake?

    Almost the same phrasing exists in the Scandinavian languages, too, except there it's “not for something/anything” instead. – Janus Bahs Jacquet Jul 20 '14 at 11:56

I've always thought of the colloquial usage of this phrase as simultaneously self-effacing and gently but firmly assertive. "What I'm about to say may not be definitive or comprehensive, but quite obviously it merits consideration."

I've heard this phrase mostly on the east coast, and it often but not always has the same flavor as "just saying...." You're leading someone to an obvious conclusion but softening it slightly.

Let me add, I like the "naught for nothing" theory. In a bunch of the northeast "not" and "naught" would sound nearly identical, so now I'm questioning what I was actually hearing all those years.
