I believe the answer is:

noses

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

'they' is the definition.
Both the answer and definition are plural nouns.
Perhaps they are linked in a way I don't understand?

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for noses that I've seen before include "Organs of smell" , "Beaks, conks" , "Pries" , "Olfactory organs" , "Schnozzles" .)

I've seen this clue in The Guardian, The Globe and Mail and The Telegraph.
