Accepted one weekend in ten (5)
I believe the answer is:
taken
'accepted' is the definition.
(taking is a kind of accepting)
'one weekend in ten' is the wordplay.
'one' becomes 'a' (a thing is one thing).
'weekend' becomes 'k' (I've seen this in other clues).
'in' is an insertion indicator.
'a'+'k'='ak'
'ak' going into 'ten' is 'TAKEN'.
(Other definitions for taken that I've seen before include "Removed, accepted" , "Removed (from a place)" , "Removed; occupied" , "Kidnapped" , "Obtained" .)
