Governors, we hear, suffering from tedium (5)
I believe the answer is:
bored
'suffering from tedium' is the definition.
Both the answer and definition are adjectives. Maybe there's a link between them I don't understand?
'governors we hear' is the wordplay.
'governors' becomes 'board' (the board is composed of governors in some orgs).
'we hear' shows a homophone (sound like).
'board' sounds like 'BORED'.
Can you help me to learn more?
(Other definitions for bored that I've seen before include "Drilled; wearied" , "Used drill on" , "Pierced" , "Palled on" , "World-weary" .)
