Doctor goes round boozer with someone of no significance (6)
I believe the answer is:
minnow
'someone of no significance' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'doctor goes round boozer with' is the wordplay.
'doctor' becomes 'mo' (medical officer).
'goes round' means one lot of letters goes inside another.
'boozer' becomes 'inn'.
'with' becomes 'w' (abbreviation).
'mo' placed around 'inn' is 'minno'.
'minno'+'w'='MINNOW'
Can you help me to learn more?
(Other definitions for minnow that I've seen before include "Not much of a catch?" , "Small fry" , "Little person" , "unimportant person" , "A fish; insignificant person" .)
