what is 'mind, body and soul' in latin?

mens, corpus et animus?

Better double check that though, I don't know anything.

corpore?

Mens corpus and animus is correct. Corpore is also correct, but it is the ablative, in latin language there are few preposition, but the final part of any word changes to tell if the word is the subject or any complement of the sentence, so for "corpus" we can have

Corpus (subject)
Corporis (Means "of the body")
Corpori (by the body)

and so on.
