As worn by Tom to go round the job centre? (4)
I believe the answer is:
coat
'as worn by' is the definition.
I can't tell whether this definition defines the answer.
'tom to go round the job centre?' is the wordplay.
'tom' becomes 'cat' (a tom is a male cat).
'to go round' means one lot of letters goes inside another.
'centre?' indicates the central letters (I've seen 'centred' mean this).
The middle of 'job' is 'o'.
'cat' enclosing 'o' is 'COAT'.
Can you help me to learn more?
(Other definitions for coat that I've seen before include "Apply layer" , "Outer garment" , "Fleece" , "Outer covering" , "Warm outerwear" .)
