...complete with opening (5)

Ross

I believe the answer is:

whole

'complete' is the definition.
(associated in meaning)

'with opening' is the wordplay.
'with' becomes 'w' (abbreviation).
'opening' becomes 'hole' (hole is a kind of opening).
'w'+'hole'='WHOLE'

(Other definitions for whole that I've seen before include "Total" , "All the components" , "Integral" , "In entirety" , "Entire, undivided" .)

I've seen this clue in The Daily Express and The Telegraph.
