Untied - rejoined! (6)

I believe the answer is:

united

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

'untied rejoined' is the definition.
I can't judge whether this definition defines the answer.

'untied rejoined' is the wordplay.
'rejoined' is an anagram indicator.
'untied' is an anagram of 'UNITED'.

Can you help me to learn more?

(Other definitions for united that I've seen before include "... we stand, divided we fall" , "See 9" , "In agreement" , "Manchester _____, current Premiership champions with..." , "Various football teams" .)

I've seen this clue in the Evening Standard.
