A short new to me one. 'deride' ( see anagram thread)

I sort of felt you cannot say: I deride you ( or this or that ).
When I tried to find sentences with the word I only saw the form 'derided' It looks as if it can't be conjugated. I tried to find out what sort of verbs are those that can't be conjugated and why.
But got lost in transitives and di- and tri- transitives
and (?)intransitive.
