An inflatable horse, dirty-looking all round (6)
I believe the answer is:
dinghy
'an inflatable' is the definition.
I can't tell whether this definition defines the answer.
'horse dirty-looking all round' is the wordplay.
'horse' becomes 'H' (abbreviation as in horse power).
'dirty-looking' becomes 'dingy' (I've seen this in another clue).
'all round' means one lot of letters goes inside another.
'h' going into 'dingy' is 'DINGHY'.
Can you help me to learn more?
(Other definitions for dinghy that I've seen before include "little boat" , "craft" , "Light rowing boat" , "vessel" , "Small open boat, maybe a rubber inflatable" .)
