It's more sensible to untangle wires (5)

Ross

I believe the answer is:

wiser

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

'it's more sensible' is the definition.
(I've seen this before)

'untangle wires' is the wordplay.
'wires' can be anagrammed to 'WISER'.
But, I am not clear how the anagram is indicated.

'to' is the link.

Can you help me to learn more?

(Other definitions for wiser that I've seen before include "Comparatively intelligent" , "A little more sage" , "More shrewd" , "Less foolish" , "more enlightened" .)
