Sound seafront feature (6)
I believe the answer is:
strait
'sound' is the definition.
(I know that sound can be written as strait)
'seafront feature' is the wordplay.
'seafront' becomes 's' (this might be a standard abbreviation of which I'm unaware).
'feature' becomes 'trait' (I've seen this in another clue).
's'+'trait'='STRAIT'
Can you help me to learn more?
(Other definitions for strait that I've seen before include "Inlet" , "Sound" , "Difficulty - strict" , "Narrow channel of the sea joining two larger bodies of water" , "Narrow strip of water between two larger ones" .)
