In Arabic, there are 12 levels of friendship.
1. Zameel — someone you have a nodding acquaintance with
2. Jalees — someone you’re comfortable sitting with for a period of time
3. Sameer — you have good conversation with them; this is where things get serious
4. Nadeem — a drinking companion (just tea) that you might call when you’re free
5. Sahib — someone who’s concerned for your wellbeing; now we’re in the real ranks of friendship
6. Rafeeq — someone you can depend upon. You’d probably go on holiday with them
7. Sadeeq — a true friend, someone who doesn’t befriend you for an ulterior motive
8. Khaleel — an intimate friend, someone whose presence makes you happy
9. Anees — someone with whom you’re really comfortable and familiar
10. Najiyy — a confidant, someone you trust deeply
11. Safiyy — your best friend, someone you’ve chosen over other friends
12. Qareen — someone who’s inseparable from you. You know how they think (and vice versa)
