The word "belives" appears to be a typo for "believes." To believe means to accept something as true, to have faith or confidence in something, or to hold a particular conviction or opinion. When someone believes in something, they regard it as valid, often without needing absolute proof.
The word "believe" comes from the Old English "beliefe," which is derived from the Proto-Germanic *ga-laubjan (to hold dear). The word has its roots in the idea of holding something dear or valuable.
