A Spanish chap covering you, we hear, in ointment (7)
I believe the answer is:
unguent
'ointment' is the definition.
(I know that ointment can be written as unguent)
'a spanish chap covering you' is the wordplay.
'a spanish' becomes 'un' ('a' in Spanish).
'chap' becomes 'gent' (both can mean a man).
'covering' means one lot of letters goes inside another.
'you' becomes 'u' (homophones).
'gent' enclosing 'u' is 'guent'.
'un'+'guent'='UNGUENT'
'we hear in' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for unguent that I've seen before include "application" , "Lotion" , "Lubricant to tune gun" , "An ointment or lubricant" , "Oily substance" .)
