Debbie inspired me to think about the different definitions, and meanings of the word 'love'.
Okay, since I am a bible freakaziod, I will start with some biblical definitions.

In the New Testament there are four distinct Ancient Greek words that English defines as the one word 'love'.

They are: agápe, éros, philía, and storg. They all have different meanings:

Agápe means "love" (unconditional love) in modern day Greek, such as in the term s'agapo (Σ'αγαπ), which means "I love you". In Ancient Greek, it often refers to a general affection or deeper sense of "true love" rather than the attraction suggested by "eros". Agape is used in the biblical passage known as the "love chapter", 1 Corinthians 13, and is described there and throughout the New Testament as sacrificial love. Agape is also used in ancient texts to denote feelings for a good meal[citation needed], one's children, and the feelings for a spouse. It can also be described as the feeling of being content or holding one in high regard. Agape was appropriated by Christians for use to express the unconditional love of God.[citation needed] Before agape love there was no other word to express such great love.[citation needed]

Éros is passionate love, with sensual desire and longing. The Modern Greek word "erotas" means "intimate love;" however, eros does not have to be sexual in nature. Eros can be interpreted as a love for someone whom you love more than the philia, love of friendship. It can also apply to dating relationships as well as marriage. Plato refined his own definition: Although eros is initially felt for a person, with contemplation it becomes an appreciation of the beauty within that person, or even becomes appreciation of beauty itself. Plato does not talk of physical attraction as a necessary part of love, hence the use of the word platonic to mean, "without physical attraction." In the Symposium, the most famous ancient work on the subject, Plato has the middle-aged Athenian philosopher, Socrates argue to aristocratic intellectuals and a young male acolyte in sexual pursuit of him, that eros helps the soul recall knowledge of beauty, and contributes to an understanding of spiritual truth, the ideal "Form" of youthful beauty that leads us humans to feel erotic desire -- thus suggesting that even that sensually-based love aspires to the non-corporeal, spiritual plane of existence; that is, finding its truth, just like finding any truth, leads to transcendence. Lovers and philosophers are all inspired to seek truth through the means of eros."

Philia means friendship or affectionate love in modern Greek. It is a dispassionate virtuous love, a concept developed by Aristotle. It includes loyalty to friends, family, and community, and requires virtue, equality and familiarity. In ancient texts, philos denoted a general type of love, used for love between family, between friends, a desire or enjoyment of an activity, as well as between lovers.

Storge means "affection" in ancient and modern Greek. It is natural affection, like that felt by parents for offspring. Rarely used in ancient works, and then almost exclusively as a descriptor of relationships within the family. It is also known to express mere acceptance or putting up with situations, as in "loving" the tyrant.
