Find is an irregular lexical verb - it has the third person form "finds", the -ing form "finding", and an irregular preterite and past participle "found". The latter two may be over-regularised to *"finded". Its pattern is the same as bind, grind and wind (turn). Find is a transitive verb, so it must take an object, i.e. you have to find something.
"Find" can undergo dative shift, e.g. "I found a pen for him" can be changed to "I found him a pen".
In criminal law, a court finds someone guilty or not guilty of a crime.
