Did husband's condoms, Elite, occasionally burst? (10)
I believe the answer is:
economised
'did husband's' is the definition.
('economise' can be a synonym of 'husband')
'condoms elite occasionally burst?' is the wordplay.
'occasionally' indicates alternate letters.
'burst?' indicates an anagram (I've seen 'burst' mean this).
The alternating letters of 'elite' are 'eie'.
'condoms'+'eie'='condomseie'
'condomseie' is an anagram of 'ECONOMISED'.
(Other definitions for economised that I've seen before include "Did husband" , "No comedies (anag.)" .)
