Show how to make a strong wine light (7)
I believe the answer is:
portray
'show how' is the definition.
'portray' can be an answer for 'show' (to portray is to show or depict). I'm unsure of the 'how' bit.
'a strong wine light' is the wordplay.
'a strong wine' becomes 'port' (strong type of wine).
'light' becomes 'ray' (ray is a kind of light).
'port'+'ray'='PORTRAY'
'to make' acts as a link.
Can you help me to learn more?
(Other definitions for portray that I've seen before include "Depict in art" , "sketch" , "Use words to describe" , "Depict, present" , "Paint a picture" .)
