Offensive type, comfortable with more extended line out (9)
I believe the answer is:
warmonger
'offensive type' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'comfortable with more extended line out' is the wordplay.
'comfortable with' becomes 'warm' (I can't justify this - if you can you should believe this answer much more).
'more extended' becomes 'longer' ('long' can be similar in meaning to 'extended').
'line' becomes 'l' (used when specifying particular lines from a poem).
'out' is a deletion indicator.
'longer' with 'l' taken out is 'onger'.
'warm'+'onger'='WARMONGER'
Can you help me to learn more?
(Other definitions for warmonger that I've seen before include "Jingoist" , "Jingoistic individual" , "Hawk" , "Bellicose person" , "Bellicose type" .)
