Cove with a bit of beach, apparently (4)
I believe the answer is:
Here is my best explanation:
'cove' is the definition.
'a bit of beach apparently' is the wordplay.
'a bit of' indicates the answer is hidden within the clue (I've seen 'a bit' mean this (the answer is formed by a bit of the clue)).
'CHAP' can be found hidden inside 'beach apparently'.
'with' acts as a link.
(Other definitions for chap that I've seen before include "Become sore; fellow", "Cracked skin patch caused by cold", "Crack - fellow", "we prefer not to have on hand", "Sore; cheek; man", "Bloke; (skin) crack", "Fellow < makes > crack", "Become raw from cold - fellow", "Cracked patch (of skin) - gentleman" and "Man; (of skin) turn sore".)
