Quote view delivered in speech (4)
I believe the answer is:
cite
'quote' is the definition.
(I know that quote can be written as cite)
'view delivered in speech' is the wordplay.
'view' becomes 'sight' (synonyms).
'delivered in speech' indicates a 'sounds like' (homophone) clue.
'sight' sounds like 'CITE'.
(Other definitions for cite that I've seen before include "Summons - quote" , "Make reference to" , "Quote (an author)" , "Quote (eg, a book)" , "Mention as example or quote" .)
