Has now cooked seconds (4)
I believe the answer is:
owns
'has' is the definition.
('own' can be a synonym of 'have')
'now cooked seconds' is the wordplay.
'cooked' indicates anagramming the letters.
'seconds' becomes 's' ().
'now' is an anagram of 'own'.
'own'+'s'='OWNS'
(Other definitions for owns that I've seen before include "Has possession of by right" , "uses" , "Confesses" , "Possesses" , "Belongs to" .)
