It's said that this is not a good idea to think in my native language (Turkish) then try to translate it to English.

But I couldn't find to correct word/phrase to express this sentence:

I didn't download any extra library except ones in the code.

Should it be ones or one's?

"One's" is a contraction of "one is" or "one has." It is also the possessive of "one." Examples of these are:

  • One's mood can be affected by the seasons. (possessive)
  • One's the smallest positive integer. (contraction)

"Ones" is merely the plural of "one." This is the usage you are looking for here. In English, "one" can sometimes be used to indicate individual units of something. Here are some examples. I've put in square brackets a translation of what "one" means in each instance:

  • They are the ones [the specific people] who bought the house.
  • I don't play video games, except ones [non-specific games] that get left at my apartment by friends.
  • I am the only one [person] who can help you.
  • She will take in any dogs, even ones (non-specific dogs) who are not housebroken.

Note also, there are small changes you can make to such phrases that alter the meaning very slightly. With your example, there could be many variations. I think the one you want is:

I didn't download any extra libraries except (for) the ones in the code.

The use of "for" here is optional.


"Ones" is the plural of "one". Example: Are those the ones you are looking for?

"Ones" is also the possessive form of "one" when "one" is used as a pronoun. There is no apostrophe, similar to "his". Example: One should mind ones own business.

"One's" is a contraction of "one" and "is", or "one" and "has".

Examples: One's less than two. One's been less then two forever.

If one is used as a proper noun or a noun, then "One's" would be the possessive for the proper noun, and one's would be the possessive for the noun.

Examples: "Number One's skills are better than Number Two's skills" or something like that. I can't think of a great example of a sentence.

Two's value is greater than one's value. (Talking about numbers with the numbers being nouns.)


You should use "ones" without the apostrophe.

You would use "one's" when referring to something belonging to oneself.

Also, you might want to use the definite article ("the ones"), or even a different pronoun ("those"). For example:

I didn't download any extra library except those in the code.
