i want to say this word in a plural way is this the correct way

boy crushes
or boys crushes

The best way to say this would be "the boys' crushes" -- because "boys" is plural and it's also possessive.

PS -- if you give us your entire sentence, you'll probably get a better answer.

my entire snetence is this :

sara looked happy going to school, but it was odd becuz she hated school. maybe it had to do with boy crushes

I think you're making up words.

Please re-type with correct punctuation, spelling, etc., and change that last to "crushes on boys."

sara looked happy going to school, but it was odd because she hated school. maybe it had do with BOY CRUSHES

Good luck.

is it right!?

Sara felt happy being at school, but at the same time she hated. The part she disliked about school were Boys having crushes on her.

This may make more sense.

The correct way to form the plural of the phrase "boy crush" depends on the meaning you intend to convey.

If you are referring to multiple boys each having a crush on someone, the correct form would be "boys crushes." In this case, "boys" functions as the plural noun modifying the noun "crushes."

For example:
- "Many boys in my class have crushes on the same girl."

If you are referring to one boy having multiple crushes on different people, the correct form would be "boy crushes." In this case, "boy" functions as a singular noun modifying the plural noun "crushes."

For example:
- "The boy has crushes on several different girls."

Remember, the choice between "boy crushes" and "boys crushes" depends on whether you are talking about multiple boys with individual crushes or a single boy with multiple crushes.
