Friendly and agreeable sort of conga line (9)

I believe the answer is:

congenial

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

'friendly' is the definition.
(similar in meaning)

'agreeable sort of conga line' is the wordplay.
'conga line' can be anagrammed to 'CONGENIAL'.
Though, I am unsure how the anagram is indicated.

'and' is the link.

Can you help me to learn more?

(Other definitions for congenial that I've seen before include "Harmonious and friendly" , "relaxing" , "Pleasant and agreeable" , "Suited to one's taste" , "Having similar interests" .)

I've seen this clue in The Times and The Sunday Times.
