- Sahib – someone who’s concerned for your wellbeing
- Rafeeq – someone you can depend upon, you’d probably go on holiday with them
- Sadeeq – a true friend, someone who doesn’t befriend you for an ulterior motive

One interesting thing I notice is that in the Bengali language, Sahib is used as an honorific, like Sir, and I suspect that it originates from the Mughal Empire and has similar roots.
