Unpunctual person getting me to clear off (9)
I believe the answer is:
latecomer
'unpunctual person' is the definition.
'latecomer' can be an answer for 'person' (latecomer is a kind of person). I am not sure about the 'unpunctual' bit.
'me to clear off' is the wordplay.
'off' is an anagram indicator.
'me'+'to'+'clear'='metoclear'
'metoclear' anagrammed gives 'LATECOMER'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for latecomer that I've seen before include "Person arriving behind time" , "Unpunctual type o" , "Perhaps one held up" , "Ace Merlot (anag)" , "Delayed arrival" .)
