Sharp pressure to abandon university before end of May (6)
I believe the answer is:
dressy
'sharp' is the definition.
(I've seen this in another clue)
'pressure to abandon university before end of may' is the wordplay.
'pressure' becomes 'duress' (I've seen this before).
'to abandon' is a deletion indicator.
'university' becomes 'U' (abbreviation for university).
'before end of may' becomes 'y' (I can't justify this - if you can you should believe this answer much more).
'duress' with 'u' taken out is 'dress'.
'dress'+'y'='DRESSY'
Can you help me to learn more?
(Other definitions for dressy that I've seen before include "(Of clothes) smart, formal" , "Smartly clothed" , "Nattily attired, wearing stylish clothes" , "(Of clothes) suitable for a smart occasion" , "Wearing stylish clothes, elegant (6)" .)
