I'll quote someone else for the definition, though I don't know who the quoter is.
"Love is patient, love is kind. Love is not jealous or boastful or proud or rude. Love does not demand it's own way. Love is not irritable, and it keeps no record of when it has been wronged. It is never glad about injustice but rejoices whenever the truth wins out. Love never gives up, never loses faith, is always hopeful, and endures through every cirucmstance. Love will last forever."
That, AND: love n. - A deep, tender, ineffable feeling of affection and solicitude toward a person, such as that arising from kinship, recognition of attractive qualities, or a sense of underlying oneness.
