own
After possessives
We only use own after a possessive word. It cannot directly follow an article.
- It’s nice if a child can have his or her own room. (not
… an own room.) - Car rental is expensive. It’s cheaper to take one’s own car. (not
… the own car.) - I’m my own boss.
a/some … of one’s own
This structure makes it possible to include a/an, some or another determiner in the phrase.
- I’d like to have a car of my own.
- It’s time you found some friends of your own.
- He’s got no ideas of his own.
own with no following noun
We cannot use mine, yours, etc with own, but we can drop a noun after my own, your own, etc if the meaning is clear.
- ‘Would you like to use my pen?’ ‘No, thanks. I can only write with my own.’ (not
… mine own.)
own and -self
The emphatic and reflexive pronouns myself, yourself, etc (see here) do not have possessive forms. My own, etc is used instead.
- I’ll do it myself, and I’ll do it in my own way. (not
… in myself’s way.) - She can wash herself and brush her own hair now. (not
… brush herself’s hair.)
on one’s own
Note the two meanings of on one’s own.
- My mother lives on her own. (without company)
- Don’t help him. Let him do it on his own. (without help)
note
For by oneself used in similar ways, (see here).
