Around lake, Barry sits in mobile home — the most prominent in field (11)
I believe the answer is:
trailblazer
'most prominent in field' is the definition.
The definition suggests a singular noun which matches the answer.
'around lake barry sits in mobile home' is the wordplay.
'around' is an insertion indicator.
'lake' becomes 'L' (geographical abbreviation).
'barry' becomes 'baz' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sits in' indicates putting letters inside.
'mobile home' becomes 'trailer' (synonyms).
'l' inserted inside 'baz' is 'blaz'.
'blaz' placed inside 'trailer' is 'TRAILBLAZER'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for trailblazer that I've seen before include "Leader in the field" , "Pioneer, innovator" , "trendsetter" .)
