Agreed I will cut eggs - a raw, green sort (6)
I believe the answer is:
rookie
'a raw green sort' is the definition.
(raw and green can both mean inexperienced)
'agreed i will cut eggs' is the wordplay.
'agreed' becomes 'ok' (eg when responding to an offer).
'will cut' indicates putting letters inside (inserted letters cut their way in).
'eggs' becomes 'roe' (fish eggs).
'ok'+'i'='oki'
'oki' inserted into 'roe' is 'ROOKIE'.
(Other definitions for rookie that I've seen before include "inexperienced fighter" , "New recruit as to army" , "new team member" , "Army or police recruit" , "Raw recruit" .)
