Quayside question cut short by bark (5)
I believe the answer is:
wharf
'quayside' is the definition.
(I've seen this before)
'question cut short by bark' is the wordplay.
'question' becomes 'why' (why is a question word).
'cut short' means to remove the last letter.
'by' says to put letters next to each other.
'bark' becomes 'arf' (I've seen this in another clue).
'why' with its final letter taken away is 'wh'.
'wh'+'arf'='WHARF'
(Other definitions for wharf that I've seen before include "Waterfront landing stage" , "Landing stage for cargo" , "Landing-stage" , "Come ashore here" , "moor" .)
