Dull ending for low-cost ceremony (5)
I believe the answer is:
trite
'dull ending' is the definition.
'trite' can be an answer for 'dull' (I've seen this before). I'm unsure of the 'ending' bit.
'low-cost ceremony' is the wordplay.
'low cost' becomes 't' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ceremony' becomes 'rite' (rite is a kind of ceremony).
't'+'rite'='TRITE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for trite that I've seen before include "Commonplace, hackneyed" , "Overfamiliar through overuse" , "used till novelty's worn off" , "Dull, unoriginal" , "Stock" .)
