What Do We Mean By The Word "love"?

"Falling in love" Do you have a scriptural foundation for this, and verses to support it. Does "falling in love" have a Biblical definition or explanation, or are you speaking from experience, or from what you have read in books or seen in movies. Not being critical, just asking. You see I am looking for what the authority is for the statements that have been made. So many just make a statement, and many accept it, but the foundation from where that statement comes is flawed. The Bible speaks of love, agape, eros, storge, phileo; and they all have different meanings. Hollywood speaks of love, and it may just be infatuation, lust, or romance, and not really any kind of Biblical love at all. Have you ever been confused on this subject, or been using the word "love" when it really wasn't love you were thinking about? Some people think they are dealing with love, get married, and find out things didn't work out the way they hoped, because they were deceived in what the understanding of love truly should have been. I welcome your comments.
