Time to greet prince going with crusader? (9)
I believe the answer is:
weeknight
'time' is the definition.
(I've seen this before)
'to greet prince going with crusader?' is the wordplay.
'to greet' becomes 'weep' (I've seen this before).
'prince' becomes 'p'.
'going' is a deletion indicator.
'with' means one lot of letters go next to another.
'crusader?' becomes 'knight'.
'weep' with 'p' taken out is 'wee'.
'wee'+'knight'='WEEKNIGHT'
(Other definitions for weeknight that I've seen before include "appears between working days" , "evening between Monday and Friday" , "Part of 67 [SENNIGHT]" , "End of working day" , "Bit of time" .)
