Bishop on a weekend getaway (5)
I believe the answer is:
break
'getaway' is the definition.
(thesaurus)
'bishop on a weekend' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'on' becomes 're' ('on' can be mean 'with reference to').
'weekend' becomes 'k' (I've seen this in other clues).
'b'+'re'+'a'+'k'='BREAK'
(Other definitions for break that I've seen before include "Interrupt - rest period" , "Fracture; holiday" , "Shatter; respite" , "Shatter; interval" , "Vacation; snap" .)
