'idea is accepted' is the definition.
I can't tell whether this defines the answer.

'although terrible' is the wordplay.
'although' becomes 'though' (synonyms).
'terrible' becomes 't' (this could be a standard abbreviation of which I'm unaware).
'though'+'t'='THOUGHT'

Can you help me to learn more?
