Better than getting one's wires crossed? (5)
I believe the answer is:
wiser
'better' is the definition.
(thesaurus)
'than getting one's wires crossed?' is the wordplay.
'wires' anagrams to 'WISER'.
However, I am not clear how this is indicated.
Can you help me to learn more?
(Other definitions for wiser that I've seen before include "showing more understanding?" , "More sensible" , "Having learned one's lesson?" , "more like Charles V" , "More shrewd" .)
