Love; it's a four letter word. It comes from Latin but its exact meaning is unknown, so there are multiple interpretations of its etymology.
According to the RAE Institution, Love is «a feeling toward another person who naturally attract us and by seeking reciprocity in the desire of union, this feeling completes us, brings us joy, and gives us the energy to live together, communicate, and create». It also implies softness and kindness.
Scientifically or psychologically speaking, Love is a brain-based motivation, like a bond. Love comes from an organ; not from heart —as everyone thinks, but from the brain.
It's also seen as an emotional experience shaped by the need to connect with someone.
Did you know that Love causes certain neurotransmitters in our brain to "explode"? You could say it's a chemical reaction involving serotonin, dopamine, norepinephrine, oxytocin, and more. It's almost like a drug, which is why it's so hard to let go. It's incredible, don't you believe it?
I don't know where I'm going with all this rambling. Or maybe I do know but I'm just playing dumb. All this time, I've been afraid to say a stronger word to you; a word so powerful that it would let you know there's nothing I wouldn't do for you.
Love, my dearest. Certainly.
