Islander, a chap reportedly in love (8)

I believe the answer is:

filipino

I'm a little stuck... Click here to teach me more about this clue!

'islander' is the definition.
(I've seen this before)

'a chap reportedly in love' is the wordplay.
'a chap reportedly' becomes 'filip' (I can't explain this - if you can you should believe this answer much more).
'love' becomes 'o' (In tennis, 'love' means 'zero').
'filip'+'in'+'o'='FILIPINO'

Can you help me to learn more?

(Other definitions for filipino that I've seen before include "Asian" , "Person from the Philippines" , "From Manila, perhaps" , "One coming from Manila?" , "Inhabitant of the Philippines" .)

I've seen this clue in The Times.
