If turning up on Tuesday, is quite suitable (3)
I believe the answer is:
fit
'quite suitable' is the definition.
'fit' can be an answer for 'suitable' (similar in meaning). I am unsure of the 'quite' bit.
'if turning up on tuesday' is the wordplay.
'turning up' says the letters should be written in reverse.
'on' is a charade indicator (letters next to each other).
'tuesday' becomes 't'.
'if' in reverse letter order is 'fi'.
'fi'+'t'='FIT'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for fit that I've seen before include "Strong" , "Paroxysm" , "Suitable; sudden attack" , "Healthy; conform to" , "Adapt; well" .)
