The only ones in Bahraini Arabic I know of (but are now old-timey and obsolete): bulīsxāna 'police station' karxāna 'sewing machine'

Bahraini Arabic word of the day ʕār, yʕūr 'to double over' خلاني اعور من الضحك xallāni āʕūr min iḏ̣-ḏ̣iḥik 'He made me double over with laughter' (I've only ever heard it in the present tense)

Earliest attestation is in a verse from the 10th century Baghdadi cookbook Kitāb al-Ṭabīkh: وأركبت ساف لحم فوق أليته وساف من بصل حلو ومن تمن 'A layer of meat underneath of which lies a layer of its own fat, and another of sweet onion, another of rice'

Another one (almost) is: Ar. ʕayn 'eye; spring' MP. čašm 'eye', čašmag 'spring'

Twitter sucks (doesn't send notifications to people I reply to and wastes my time), and I remembered that this place exists. Wow, a lot of names I haven't seen in ages here
