Pacific characters promote it for a bit, we hear (5)
I believe the answer is:
peace
'pacific characters promote it' is the definition.
I can't judge whether this definition defines the answer.
'bit we hear' is the wordplay.
'bit' becomes 'piece' (synonyms).
'we hear' indicates a 'sounds like' (homophone) clue.
'piece' is a homophone of 'PEACE'.
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for peace that I've seen before include "Freedom from disturbance, tranquillity" , "Repose, tranquillity" , "''And I shall have some ... there, for ... comes dropping slow'' (WB Yeats)" , "Absence of war" , "Accord" .)
