Passed girl going through dictionary (6)
I believe the answer is:
okayed
'passed' is the definition.
(okaying is a kind of passing)
'girl going through dictionary' is the wordplay.
'girl' becomes 'kay' ().
'going through' indicates putting letters inside.
'dictionary' becomes 'OED' (Oxford English Dictionary).
'kay' inserted into 'oed' is 'OKAYED'.
(Other definitions for okayed that I've seen before include "Sanctioned" , "Gave informal approval" , "Informally approved and agreed" , "Allowed" , "Authorised" .)
