Bearing costs centrally, cutting 100% (7)
I believe the answer is:
posture
'bearing' is the definition.
(I know that bearing can be written as posture)
'costs centrally cutting 100%' is the wordplay.
'centrally' says to take the centre.
'cutting' is an insertion indicator (some letters cut their way into a word).
'100%' becomes 'pure' (100% can mean pure or unadulterated).
The centre of 'costs' is 'ost'.
'ost' inserted into 'pure' is 'POSTURE'.
(Other definitions for posture that I've seen before include "Body positioning" , "Body position" , "Bodily position" , "The way a person stands or sits" , "Bodily stance" .)
