Thus male has no time for self-denial, being languid (9)
I believe the answer is:
somnolent
'languid' is the definition.
(thesaurus)
'thus male has no time for self-denial' is the wordplay.
'thus' becomes 'so' ('so' can be a synonym of 'thus').
'male' becomes 'm' (common abbreviation).
'has' says to put letters next to each other.
'time for self-denial' becomes 'lent' (reference to fasting in Lent).
'so'+'m'+'no'+'lent'='SOMNOLENT'
'being' acts as a link.
(Other definitions for somnolent that I've seen before include "Drowsy - lost on men (anag)" , "drifting off" , "Sleepy, drowsy" , "Lent moons (anag.)" , "Dozy" .)
