Seizures of suits (4)
I believe the answer is:
fits
I believe this is a double definition.
'seizures' is the first definition.
(fit is a kind of seizure)
'suits' is the second definition.
('fit' can be a synonym of 'suit')
'of' is the link.
(Other definitions for fits that I've seen before include "Prepares" , "Seizures" , "Paroxysms" , "short bouts" , "feels comfortable" .)
