Love does not have any full form i.e it is not an acronym for anything, it is complete as it is. But since the question is asking for what would be my own full form if the word LOVE were to be an acronym, I will definitely try my best. Love as a word, is a powerful concept among mankind.
Whatever you say about it and anyway you define it, is definitely how it occurs to you. Love is a word used to express feelings and affection to someone. It is a perfect word to use when trying to tell someone you truly care about him or her. This word is common about youth and it is a sad thing to see people using the word in a bad way. Many people are using it to deceive vulnerable people around them. However if I were to make a full form of the word LOVE, it would be: Lot Of Values without Ends.
There are some people who still believe that out of all the things that are available in this world, love still has to be the most important thing. What if the word love is an abbreviation? What words are you going to use in order to describe love? I would say that it can be for Leaning On Voracious Endearment.
Some people will find it hard to forget love especially since they have already felt it. At the same time, it can be hard for people to force love when they do not feel it. There may be some scientific explanations for this and why people feel in love towards other people but once people feel it, they will know what it is.
This word of only four letters is one of the most important human attributes. It is difficult to do it justice as an acronym for four words but my attempt would be: Looking Over Vivacious Emotion. I am sure others could do better.
