Ceremony after time is banal (5)
I believe the answer is:
trite
'banal' is the definition.
(I've seen this before)
'ceremony after time' is the wordplay.
'ceremony' becomes 'rite' (rite is a kind of ceremony).
'after' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'rite' put after 't' is 'TRITE'.
'is' acts as a link.
(Other definitions for trite that I've seen before include "Banal, commonplace" , "used till novelty's worn off" , "repeated too often" , "(Of an idea) lacking in originality" , "Lyre string" .)
