Start by defining what is a word, what can you do with words, the history of words, what are the most common used words.
Than define what is love, what shapes and forms it can come in, what is the history of it.
After defining those two i think you'll have a better understanding what the relationship between the two.
And if you still don't know just ask yourself how can i define love? what words can i use to define it? what other people think about it ?
What is the relationship between words and love ?
I having an eassy and this is my topic I have no clue where to even start.
