Husband sat, training bowlers, say (4)
I believe the answer is:
hats
'bowlers say' is the definition.
(bowler is a type of hat)
'husband sat training' is the wordplay.
'husband' becomes 'h' (abbreviation).
'training' is an anagram indicator (to train can mean to grow something into a shape).
'sat' anagrammed gives 'ats'.
'h'+'ats'='HATS'
(Other definitions for hats that I've seen before include "Headwear" , "Headgear" , ""Porkpie" and "pillbox" attire" , "Headdresses" , "Milliner's stock" .)
