craic

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

'cork's fun?' is the definition.
The definition suggests an adjective which matches the answer.

'king pair essentially the end of dominic' is the wordplay.
'king' becomes 'CR' (short for Carolus Rex, King Charles in Latin).
'essentially' indicates the central letters.
'the end of' indicates one should take the final letters.
The centre of 'pair' is 'ai'.
The final letter of 'dominic' is 'c'.
'cr'+'ai'+'c'='CRAIC'

Can you help me to learn more?
