Maxiphilotic
A word made to describe only the deepest of love, be it of parental, friendship, but most primarily that of romantic love. The prefix, Maxi- means of the highest intensity, -philo-, meaning loving, and -otic, meaning the condition. The literal definition being "the condition of being in the highest intensity of love". The word itself can, however, mean the deepest and otherwise most indescribable feelings a person(s) can give you.
