The greeks had
many words for love. English has just the one 'cause we're frugal like that, but there are many concepts inherent in the one word. Here's how I break it down.
Family love
The love for people in your family. Pretty basic concept. Unlike other forms of love this has less of choice and more of duty in it's makeup. this love is somewhat hardwired, especially for offspring. You can dislike someone in your family and still love them. It is of course possible for someone to be enough of a screwup that they can alienate even family love.
Friend love
There are acquaintances, and friends, and some friends grow so close and essential that you love them. This form of love is the most purely of choice. Like taken to it's logical conclusion. A friend helps you move, a friend who loves you helps you move bodies.
Romantic love
This is what it means to be "in love." This the love of which poets write. True love of burning passion and endless pain. What drove romeo and juliet to their graves and what everyone hopes for. In polyamoury, this is the kind of multiple simultaneous loves it means.
Conceptual love
This is the love of a idea instead of a particular embodiment. One can love apples, doesn't mean you love a specific apple, but rather apples in general. When i say, "I love my browncoats" means I love them as a whole. I may love specific browncoats, and not love others, but as a group I love them.
