Fishy end to an aeroplane? (3)
I believe the answer is:
fin
'aeroplane?' is the definition.
(thesaurus)
'fishy end to an' is the wordplay.
'fishy' becomes 'fi' (I can't explain this - if you can you should believe this answer much more).
'end to' says to take the final letters.
The final letter of 'an' is 'n'.
'fi'+'n'='FIN'
Can you help me to learn more?
(Other definitions for fin that I've seen before include "Fish propeller; end (Fr.)" , "Found on a fish" , "Paddle-like organ" , "Part of an aircraft's tail" , "A fish uses it to steer itself" .)
