What kinds of words should you check for a possible missing final "s"?

Question

Just need some help for the one on top.

Answer 1

hmmm... i don't think i really understand this question. can you add some more details? are you asking us regarding proofreading? which words should we make sure isn't missing an S at the end?

if it's plural, it needs an S, but i don't think that's what you're asking...
