Ointment's covering most of feline's spots (9)
I believe the answer is:
locations
'spots' is the definition.
(I've seen this in another clue)
'ointment's covering most of feline's' is the wordplay.
'ointment's' becomes 'lotions' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'covering' indicates putting letters inside.
'most of' means to remove the last letter.
'feline' becomes 'cat' (cat is a kind of feline).
'cat' with its final letter taken away is 'ca'.
'lotions' going around 'ca' is 'LOCATIONS'.
Can you help me to learn more?
(Another definition for locations that I've seen is " Places, sites".)
