Fully occupy Phil, say (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
fill
'fully occupy' is the definition.
'fill' can be an answer for 'occupy' (synonyms). I'm not sure about the 'fully' bit.
'phil say' is the wordplay.
'say' indicates a 'sounds like' (homophone) clue.
'phil' is a homophone of 'FILL'.
Can you help me to learn more?
(Other definitions for fill that I've seen before include "Appoint person to (post)" , "Top up" , "Be suitable - . . . . the bill" , "Completely occupy" , "` `Work expands to .... the time available' '" .)
