A mix of emotions, behaviors, and beliefs associated with strong feelings of affection, protectiveness, warmth, and respect for another person.

Love can also be used to apply to non-human animals, to principles,  and to religious beliefs. For example, a person might say he or she  loves his or her dog, loves freedom, or loves God.

Love has been a favored topic of philosophers, poets, writers, and  scientists for generations, and different people and groups have often  fought about its definition.
