It depends on whether you are simply using the plural noun (no apostrophe) or forming a possessive (with an apostrophe). Examples:
I'd
The contraction for "they are" would be they're.
The apostrophe spelling he's is a contraction of the phrase "he is."The possessive pronoun for "he" would be his.
Parents (no apostrophe) is plural.Parent's (apostrophe s) is singular possessive.Parents' (s apostrophe) is plural possessive.
It would be Dr's order, but I would spell out the word. "Doctor's order".
dare'ot is how you spell dare not with an apostrophe
I'd
This is spelt "apostrophe".
bosses'
Parents'......the apostrophe goes at the end of Parents because it is Plural Possessive.
