المعنى
To express immense gratitude, more emphatic than 'thank you'.
خلفية ثقافية
In Iran, 'bi-nahāyat mamnunam' is often the first step in a Ta'arof exchange. The other person will likely respond with 'khāhesh mikonam' (I beg [you not to mention it]) or 'vazife-am bud' (it was my duty). While 'mamnun' is understood, Dari speakers often prefer 'tashakkor' or 'besyār tashakkor'. 'Bi-nahāyat' is used but sounds more like 'Tehrani' Persian to Afghan ears. Tajik Persian uses 'Rahmat' (from Arabic Mercy) more frequently for thanks. 'Bi-nahāyat mamnunam' would be understood as very formal or literary. In the US or Europe, younger generations might mix this with English: 'Bi-nahāyat mamnun for everything!' It remains a way to maintain a connection to Persian politeness even when speaking 'Pinglish'.
The Hand Gesture
When saying this in person, place your right hand over your heart. It adds a layer of sincerity that words alone cannot convey.
Don't Overuse
If you say this for every small thing, it loses its power. Save it for moments that truly deserve 'infinite' gratitude.

No, 'bi-nahāyat' is an adverb. It needs to describe something. You must say 'bi-nahāyat mamnun' or 'bi-nahāyat sepasgozar'.
'Mamnun' is more common and has Arabic roots. 'Sepasgozar' is more formal and has Persian roots. Both work with 'bi-nahāyat'.
Change the ending to '-im': 'Bi-nahāyat mamnunim' (بینهایت ممنونیم).
Yes, it's very common in texts, often written as 'بی نهایت ممنون' (dropping the 'am' in very casual typing, though 'mamnunam' is better).
No, it is a purely secular expression of gratitude, though it uses words that can appear in religious texts.
Yes! You can say 'bi-nahāyat khosh-hal' (infinitely happy) or 'bi-nahāyat ziba' (infinitely beautiful).
It's a high-level Ta'arof. It means 'I am so grateful that I feel guilty for the trouble I caused you'. You can use both together.
In casual spoken Tehran Persian, 'merci' is very common. But for serious gratitude, 'mamnun' or 'bi-nahāyat mamnunam' is preferred.
It's a soft 'h' like in 'house'. Don't skip it, but don't make it too harsh.
