Illustrate harbour with some light (7)
I believe the answer is:
portray
'illustrate' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'harbour with some light' is the wordplay.
'harbour' becomes 'port' (I've seen this before).
'with' means one lot of letters go next to another.
'some light' becomes 'ray' (ray is a kind of light).
'port'+'ray'='PORTRAY'
Can you help me to learn more?
(Other definitions for portray that I've seen before include "Depict, present" , "Show" , "Delineate" , "Act" , "sketch" .)
