Being foolish, we start trouble (3)

I believe the answer is:

wet

'being foolish' is the definition.
(thesaurus)

'we start trouble' is the wordplay.
'start' indicates taking the first letters.
The first letter of 'trouble' is 't'.
'we'+'t'='WET'

(Other definitions for wet that I've seen before include "Saturated; rainy" , "Soaked with water" , "Damp" , "Rainy (weather)" , "Moist or Soaked" .)

I've seen this clue in the Evening Standard.
