What helps one see travelling dandy going round well-dressed (7)
I believe the answer is:
foglamp
'what helps one see travelling' is the definition.
I can't tell whether this defines the answer.
'dandy going round well-dressed' is the wordplay.
'dandy' becomes 'fop' (synonyms).
'going round' means one lot of letters goes inside another (some letters go around others).
'well dressed' becomes 'glam' (I can't justify this - if you can you should give a lot more credence to this answer).
'fop' placed around 'glam' is 'FOGLAMP'.
Can you help me to learn more?
(Other definitions for foglamp that I've seen before include "type of light" , "Strong car headlight" , "Vehicle feature to aid bad weather visibility" , "Bright light used in poor driving conditions" .)
