Form of transport like a small ship (3)
I believe the answer is:
ass
'form of transport' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'a small ship' is the wordplay.
'small ship' becomes 'ss' (this might be a standard abbreviation I've not previously seen).
'a'+'ss'='ASS'
'like' is the link.
Can you help me to learn more?
(Other definitions for ass that I've seen before include "Donkey or foolish person" , "Pompous fool or beast of burden" , "Clot" , "Horse hybrid" , "Dolt" .)
