Who came up with the word 'love' and what is your meaning of it?

Who invented love is a long story so just go here to know who invented it.. https://www.psychologytoday.com/blog/the-heart-it-all/201104/the-day-love-was-invented

Also, my definition of love is.. Someone you care about and would cry for. I love my mother, I would cry for her if she died. Or I would cry for my boyfriend.. If I ever get one. :P
