Should I put an apostrophe in "for all its worth"? The meaning comes to about the same thing either way, as far as I can make out, and it seems like "it's" is more popular. But is there an accepted version? Or any reason for preferring one over the other, other than staying conventional?

    By the way, I did read the question What's the evolution of the phrase “milk it for all its worth”?. It was asked and answered on the basis of the verb milk. The OP did ask an ancillary question about the apostrophe, but that question (my question) was not answered by anything but personal opinion/experience, google hits, and two quotes from the OED entry on "milk".

    Both could be correct depending on how you view all. If you view all as a predeterminer, then it would be its, but if all is a pronoun followed by a relative clause, then it would be it's. Commented Aug 14, 2014 at 4:34

    @brasshat Where does it answer my question? I understand the difference between it's and its - I'm not asking if they have the same meaning. I'm asking which is correct/accepted in for all it's worth. And why, if applicable.

    @SrJoven That other question was the first thing I thought of when I saw this one. It's interesting that this works with "For all its worth"/"For all it's worth", but not with "For what its worth"/"For what it's worth". Commented Aug 14, 2014 at 15:12

Apparently, the writer's intention was always to mean "it is," not "its." (A hasty conclusion and a sweeping statement, yes.)

Comparing "for all it's worth" and "for all its worth" with "for all it is worth," and considering that apostrophe use for the genitive was in fact an after thought.


enter image description here

The arrival of the apostrophe as possessive indicator confused both the writer and the reader, so that today more often than not, authors do not know which is the "original idiom" and the reader is not sure what the author had meant to say.

The safest approach for writers would be to avoid the apostrophe altogether in this case and be specific, and for the reader to rely on context where needed and possible.

    Note that in the similar expression "for what it's worth", the genitive "its" doesn't work. That's a different case, but would also suggest that "all it is worth" would be more common. Commented Aug 14, 2014 at 15:15

  • Yes! I always thought it was "for all it is worth", not "for all the worth belonging to it". Your graph seems to confirm that.

"For all it's worth" wins in my opinion as it is more adaptable to other sentences also.

"For what it's worth" for example doesn't make sense if changed to "For what its worth". That might make one wonder "For what, its worth?"

It ultimately depends on what "it" is. Does it own the worth? Or is it simply worth the worth?


Depending on whether there is an apostrophe, the phrase has two quite different meanings, and that is what needs to be explored further.

'For all it's worth' suggests the thing is not worth much. And what you are intending, 'for all it's worth', is a way of minimising the importance of the task.

When you 'use something for all its worth', the thing may well be, and probably is, worth a lot. For example if I am a politician and someone important says something nice about me, I might decide to refer to the matter as much as I possibly can and hence 'milk it for all its worth'.

    Do you have some references to validate the difference in meaning? To me, "milk it for all it's worth" is identical in meaning to "milk it for all its worth".

  • @talrnu Yes I did think about this further. There is overlap here. You are right that those two are more or less identical in meaning. But 'it's worth' does mean 'it is worth', whereas 'its worth' is 'the worth of it'. So saying 'I would throw it away, for all it is worth' is different to saying 'I would hold on to it given the worth of it'. These sentences place quite a different value on the worth of the item in question.

  • @WS2 Do you think that "for what it's worth" (where "its" is not an option) more clearly minimizes the importance of something? Commented Aug 14, 2014 at 15:16
  • Your two contrasting examples, "I would throw it away" and "I would hold on to it," are different because of what you would do with it, not because of a distinction of "the worth it has" and "the value which it is worth." Commented Aug 14, 2014 at 15:37
  • @iamnotmaynard I was just providing instances of where I would use 'it's worth' and 'its worth'. And that is how it turned out. I can't imagine using the former for something valuable nor the latter for something trivial. But that's just me.

I think it depends on the context. If you're referring to specific attributes of the object and its value, then you use "its". Usually these values are not defined by units like money, and are subjective. However, if you're referring to the object's overall value - for example, its value on the market - then you use "it's". However, I really do not think there is a solid rule for apostrophe use in this case, and I suppose that it is arbitrary for most.

    True, but the question is what was it "actually," originally, historically, and "correctly."

This is mostly a matter of distinguishing between having worth ("all its worth") and being worth something ("all it's worth"). I can only find subjective arguments for the value of either case over the other.

  • I neglected to mention that the it's form wouldn't make sense with "of". Possibly "which", though: for all which it's worth. But this feels clumsy.

    Commented Aug 14, 2014 at 14:24
  • The answer you linked specifies that "of" is optional with "all", "half", or "both". Still, including it here would help distinguish the meaning from "for all it is worth".

    The term "pronoun" is sometimes used to refer to things that aren't nouns but are associated with pronouns (especially adjectives such as "its"). The adjective "its" is not the same thing as the pronoun "it". When used with countable nouns, "all of its Xs" has a different shade of meaning from "all its Xs"; the former applies to Xs individually, and the latter collectively.

As others have noted....it depends.

When you use the sentence, if you can insert the word "that" ("for all that it is worth") and have it still make sense in the way that you are using it, then you need an apostrophe to contract "it is" to "it's". If the word "that" makes no sense in the way you're using your sentence, then you need to leave out the apostrophe so that you are using the possessive "its".

  • I agree, that's a good way to tell. And the its alternative would allow inserting the word "of", so depending on what you want to say: "for all that it is worth" (contract to it's) or "for all of its worth" (no apostrophe) Commented Aug 20, 2014 at 6:30

As above, it depends, but WS2 brings up a good point that is probably easier to understand by replacing 'it' with 'he', namely, making the debate: "for all he's worth" vs. "for all his worth".

The former statement has the implication that "he" is not worth a lot, while the latter statement implies a sense of greater value. This may be due to the fact that the former statement implies that "he" can be converted to a pure monetary value, and has no value beyond that, while the latter statement creates a sense that "he" contains additional humanistic values that cannot be measured in monetary units, such as strength of character, intellect, wisdom, etc.

Thus, depending on the sense of worth/tone you wish to convey, you may wish to use "it's" for something of more concrete value, and "its" for something more abstract. Considering that "it" typically refers to objects that can be valued in monetary terms, and is frequently used in the context of "milking something for all it's/its worth" I would usually default to "it's" when in doubt.
