Did you know that Greek actually has a ton of words for love?
Here's a really basic break down:
The love of God for man and of man for God.
"Love, mostly of the sexual passion."
"Affectionate regard, friendship," usually "between equals."
"Love, affection" and "especially of parents and children"
It is also known to express mere acceptance or putting up with situations, as in "loving" the tyrant. This is also used when referencing the love for ones country or a favorite sports team.
