'renounces' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?

'key cuts' is the wordplay.
'key' becomes 'esc' ('Escape' key on a computer keyboard).
'cuts' becomes 'hews' (I've seen this in another clue).
'esc'+'hews'='ESCHEWS'

Can you help me to learn more?

(Other definitions for eschews that I've seen before include "Avoids or abstains from" , "Deliberately avoids using" , "Avoids or shuns" .)

I've seen this clue in The Independent.
