What is the Full Form of LOVE ?

LOVE actually does not have any full form, but different people create their own different full forms according to their situation, like this one -

L - Life's
O - Only
V - Valuable
E - Emotion

OR

L - Lake of sorrow
O - Ocean of tears
V - Valley of death
E - End of life

Love gets different forms, for different people, in different situations. Like for a Mother it takes a different form, for wife and children it takes another and so on. It can refer to a variety of different feelings, states, and attitudes.

It also depends on the entity like a person, food, or an electronic device. Like we can say :-
For a person - "I love my Wife"
For a food  - "I love to eat cheese burger"
For a device - "I love my mobile phone"
