Carter out in Egypt holds standard (7)
I believe the answer is:
routine
'standard' is the definition.
(I've seen this before)
'carter out in egypt holds' is the wordplay.
'holds' says the answer is hidden in the clue.
'ROUTINE' is hidden within 'carter out in egypt'.
(Other definitions for routine that I've seen before include "Set sequence of dance steps" , "Normal course of action" , "Usual pattern of actions" , "Schedule, standard procedure" , "Nine to five?" .)
