Here are my suggestions:
1. Adoration - Latreia [pronounced la-TREE-a]
2. Infatuation/Obsession - Emmone [pronounced em-MON-ee]
3. Passion - Pathousa [pronounced path-OO-sa]
4.
Desire - Himera [pronounced ee-MER-a]
5. Lust -
Erato (Eratos would be a male name in Greek)
6. Affection/Fondness/Endearment - Storge [pronounced: Stor-YEE]
7. Devotion - Eulabeia [pronounced ev-LOVE-ia]
Vocabulary-wise, the old Greek tongue is almost identical with contemporary Greek. The grammar is obviously much different. Its a bit like comparing Shakespearian English with modern English.
