A rhyme? Quite - but it's hackneyed (5)
I believe the answer is:
trite
'hackneyed' is the definition.
(I know that hackneyed can be written as trite)
'a rhyme? quite but it's' is the wordplay.
I cannot quite understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
The remaining letters 'rite' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for trite that I've seen before include "(Of an idea) lacking in originality" , "Stock" , "all vigour is gone" , "Overfamiliar through overuse" , "used till novelty's worn off" .)
