OK, I think this is kind of a stupid prompt. I don't think that my definition of love is that different or that much more interesting than anyone else. If you asked me what "meaning" means, that would be different. So let's get deep and talk about defining love.
Love is the feeling you get at six o'clock in the morning when you get dressed in the dark so you don't wake your spouse. It's when you let the other person play video games while you cook dinner. And you can feel this way about plenty of people, and I think that's really great, that you can love lots of people.
So maybe your definition wouldn't include anything about video games or cooking or waking up early or whatever, but it's all the same feeling.
