Snaps "Black ties are out!" (5)
I believe the answer is:
bites
'snaps' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'black ties are out' is the wordplay.
'black' becomes 'b' (as in pencil classifications).
'are out' indicates an anagram (out can mean wrong or inaccurate).
'ties' with letters rearranged gives 'ites'.
'b'+'ites'='BITES'
Can you help me to learn more?
(Other definitions for bites that I've seen before include "Mouthfuls" , "Nibbles" , "Morsels" , "Stings" , "Nips to" .)
