Is suitable for seizures (4)
I believe the answer is:
fits
I believe this is a double definition.
'is suitable for' is the first definition.
(I've seen this in another clue)
'seizures' is the second definition.
(fit is a kind of seizure)
(Other definitions for fits that I've seen before include "Is of the right shape and size" , "Prepares" , "Sudden uncontrollable attacks" , "short bouts" , "Seizures" .)
