Hard part's admitting addict's head for addictions (6)
I believe the answer is:
habits
'head for addictions' is the definition.
'habits' can be an answer for 'addictions'. I am unsure of the 'head for' bit.
'hard part's admitting addict's' is the wordplay.
'hard' becomes 'h'.
'part's' becomes 'bits' (bit is a kind of part).
'admitting' means one lot of letters goes inside another.
'addict's' becomes 'a' (this might be a standard abbreviation I've not previously seen).
'h'+'bits'='hbits'
'hbits' placed around 'a' is 'HABITS'.
Can you help me to learn more?
(Other definitions for habits that I've seen before include "Nuns or monks uniforms" , "Customs in nun's clothing?" , "Customs or robes" , "Customs or monk's gowns" , "Monks' and nuns' clothing" .)
