A change of word order during reading (9)
I believe the answer is:
inversion
'a change of word order' is the definition.
(rhetorical technique)
'during reading' is the wordplay.
'during' becomes 'in' (e.g. during February means in February).
'reading' becomes 'version' (a reading can be an interpretation or version).
'in'+'version'='INVERSION'
(Other definitions for inversion that I've seen before include "The opposite of" , "upsetting change" , "turning around" .)
