Different line for a fatheaded marine, possibly? (7)
I believe the answer is:
fireman
'different line' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'fatheaded marine possibly?' is the wordplay.
'fatheaded' becomes 'f' (this could be a standard abbreviation of which I'm unaware).
'possibly?' is an anagram indicator (I've seen 'possibly' mean this).
'marine' anagrammed gives 'ireman'.
'f'+'ireman'='FIREMAN'
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for fireman that I've seen before include "he puts out at work" , "Red engine driver" , "Rescue worker" , "Steam engine worker" , "Locomotive stoker" .)
