Audibly recognise certain beach (8)
I believe the answer is:
seashore
'beach' is the definition.
(I've seen this before)
'audibly recognise certain' is the wordplay.
'audibly' indicates a 'sounds like' (homophone) clue.
'recognise' becomes 'see' (I've seen this before).
'certain' becomes 'shore' (I am not sure about this - if you are sure you should believe this answer much more).
'see' sounds like 'sea'.
'sea'+'shore'='SEASHORE'
Can you help me to learn more?
(Other definitions for seashore that I've seen before include "She sells seashells on it" , "Coastal land's edge" , "where holidaymakers gather?" , "Coast, of an ocean say" , "Coast, stand" .)
