Weep over pint in church cellar (5)
I believe the answer is:
crypt
'church cellar' is the definition.
(I've seen this before)
'weep over pint' is the wordplay.
'weep' becomes 'cry' (synonyms).
'over' says to put letters next to each other.
'pint' becomes 'pt'.
'cry'+'pt'='CRYPT'
'in' acts as a link.
(Other definitions for crypt that I've seen before include "Underground cell" , "Sepulchre" , "Tomb" , "Underground church vault" , "Church basement" .)
