abnegates

I'm a little stuck... Click here to teach me more about this clue!

'rejects' 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?

'seat began to produce' is the wordplay.
'to produce' indicates an anagram.
'seat'+'began'='seatbegan'
'seatbegan' is an anagram of 'ABNEGATES'.

Can you help me to learn more?
