In audition, why chat about craft? (5)
I believe the answer is:
yacht
'craft?' is the definition.
(I know that yacht is a type of vessel)
'in audition why chat about' is the wordplay.
'in audition' shows a homophone (sound like) (audition can mean hearing).
'about' is an anagram indicator.
'why' is a homophone of 'y'.
'chat' with letters rearranged gives 'acht'.
'y'+'acht'='YACHT'
(Other definitions for yacht that I've seen before include "Light, fast sailing-vessel" , "Cathy (anag.)" , "Sailing craft" , "Small pleasure boat" , "Pleasure craft" .)
