I have been working towards compiling the primary forms of love in Greek and have came across eros, agape, philautia, storge, philia, mania, paichnidia and merika. Through a fair amount of research behind the etymology and philology behind the meanings I have found that pragma and ludus do not mean what some people/websites claim they mean. (Pragma meaning "thing" and ludus being of latin origin not Greek)
My question thus is what are the primary forms of love in Greek (are the ones I currently have accurate?) and are they different enough from the English language to give a more comprehensive understanding of "love"?
