Cause unruly ladies to be separated (8)

I believe the answer is:

isolated

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

'cause unruly' is the definition.
I can't judge whether this definition defines the answer.

'ladies to be separated' is the wordplay.
'be separated' indicates an anagram (letters separated and rearranged).
'ladies'+'to'='ladiesto'
'ladiesto' anagrammed gives 'ISOLATED'.

Can you help me to learn more?

(Other definitions for isolated that I've seen before include "Placed apart from others" , "Off the beaten track" , "kept apart from others" , "Cut off, remote" , "Solitary" .)

I've seen this clue in The Globe and Mail.
