Crossword Genius

They identify Latin quotations (4)

Ross

I believe the answer is:

tags

I'm a little stuck... Click here to teach me more about this clue!

'they' is the definition.
Both the definition and answer are plural nouns.
Maybe you can see an association between them that I can't see?

'identify latin quotations' is the wordplay.
'identify' becomes 'tag' (I've seen this in other clues).
'latin quotations' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'tag'+'s'='TAGS'

Can you help me to learn more?

(Other definitions for tags that I've seen before include "trite Latin quotations" , "They are able to identify" , "Labels; quotations" .)
