See fit to communicate (5)
I believe the answer is:
cable
'communicate' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
'see fit' is the wordplay.
'see' becomes 'c' (the word for the letter, according to Chambers).
'fit' becomes 'able' ('able' can be similar in meaning to 'fit'**).
'c'+'able'='CABLE'
'to' is the link.
Can you help me to learn more?
(Other definitions for cable that I've seen before include "Wire, flex" , "Strong line" , "Telegram; thick rope" , "Conductor for transmitting electric power" , "Rope; message" .)
