Cove admitted transposing? (5)
I believe the answer is:
inlet
'cove' is the definition.
(synonyms)
'admitted transposing?' is the wordplay.
'admitted' becomes 'in' (eg someone might be admitted into a group).
'transposing?' becomes 'let' (I can't justify this - if you can you should give a lot more credence to this answer).
'in'+'let'='INLET'
Can you help me to learn more?
(Other definitions for inlet that I've seen before include "Coastal feature" , "bit of a lake here?" , "Bay, bight" , "Arm off a larger body of water between headlands" , "Entry port" .)
