I am reasonably certain that once, glancing over a long list of English idioms, I saw an idiom that I now remember as "walk on a branch" and cannot find anywhere, so my memory must be wrong.

The listed meaning was "to give it a long shot", "to make a not-necessarily-educated guess", the implication being that it is similar to stepping on a tree's branch that may crack under you foot.

I cannot look this idiom up anywhere, to the point where I am starting to doubt it even existed.

It was not:

Does it exist, and if so, what is it?

    I might be going out on a limb here, but would it be "going out on a limb"?

  • @Hellion Hmm... I certainly did consider it when writing up the question, but ended up not including it because its meaning - "to express an unpopular opinion", "to go against the group" - seemed less close than that of the others. Now looking at some other sources, it seems like it may be the one, and the meanings I looked up for it earlier are not even listed there.

    Going out on a limb means to take a risky chance, not specifically negative. Jan 2, 2020 at 20:21

    @GSerg A common usage of go out on a limb is to preface expressing a delicate opinion or suggestion, but this is just a frequent use, not the core meaning, which is indeed, to take a risk. Jan 2, 2020 at 20:47
  • @Hellion - This is reminding me of a Kids in the hall sketch

1 Answer 1


I think you are looking for go out on a limb.

As freedictionary.com puts it:

To do or say something that lacks evidence or support.

Or, as Wiktionary says:

  • (idiomatic) To take a risk.
  • (idiomatic) To hazard a guess

KnowYourPhrase.com agrees almost completely with Wiktionary:

  1. Putting yourself in a risky or precarious situation in order to help someone.

  2. Taking a wild guess at something or expressing an opinion that might not be shared by others.
