Thriftily manage hot American group (7)
I believe the answer is:
husband
'thriftily manage' is the definition.
'husband' can be an answer for 'manage' (I've seen this before). I am not certain of the 'thriftily' bit.
'hot american group' is the wordplay.
'hot' becomes 'h' (abbreviation eg on taps).
'american' becomes 'us' (abbreviation for United States).
'group' becomes 'band' (band can mean a group of people).
'h'+'us'+'band'='HUSBAND'
Can you help me to learn more?
(Other definitions for husband that I've seen before include "Conserve" , "Be thrifty with" , "Woman's matrimonial partner" , "Partner; use carefully" , "Economically manage" .)
