Wants deposit (after home on the coast) (9)
I believe the answer is:
longshore
'on the coast' is the definition.
I can't tell whether this defines the answer.
'wants deposit after home' is the wordplay.
'wants' becomes 'longs' (longing is a kind of wanting).
'deposit' becomes 'ore' (I have seen 'Deposit of mine' mean 'ore' so perhaps 'deposit' could also mean 'ore').
'after' is a charade indicator (letters next to each other).
'home' becomes 'H' (abbreviation as used in sports fixtures).
'ore' put after 'h' is 'hore'.
'longs'+'hore'='LONGSHORE'
Can you help me to learn more?
(Other definitions for longshore that I've seen before include "very close to the sea" , "Relating to the land bordering the sea" .)
