More sensible form of snare (5)

I believe the answer is:

saner

'more sensible' is the definition.
(I've seen this in another clue)

'form of snare' is the wordplay.
'form of' indicates anagramming the letters (another form of the same letters).
'snare' is an anagram of 'SANER'.

(Other definitions for saner that I've seen before include "Less mad" , "less as hatter?" .)

I've seen this clue in the Evening Standard.
