1) Eilistraee knows all the drow words for love, and the elvish ones, too. The Drow words are: alurlssrin = unselfish, deep love raggath = act of love (lovemaking) lurraggath = act of love (sacrificial or noble deed) #Realmslore

2) ssinssrigg = passion, lust, greed, longing, love And the Elvish words are: arkhlavae = lovemaking evae = love, absence of malice immaea = familial love, loyalty to kin and family #Realmslore

3) immeeira = act or demonstration of love (deed, testimonial or honour, not lovemaking) nor = love, essence of passion Incidentally, one nickname her six Sisters have for Eilstraee is "Darkfire-Of-Love" #Realmslore

Exactly. There's a huge difference between drow communities (like Menzo) in Lolth's thrall, and all drow. There are many drow who do not reverence the Spider Queen, and don't live with warring houses led by matrons. One must always be mindful of whose voice Realmslore comes from.

In Menzo, there were drow who knew the words for love, but never dared use them. Zak, and various brothers and sisters who dared feel affection for each other despite the sisters being culturally the "enforcers" upon their brothers, or the same between parents and children.
