Why are the Roma called Roma & in Asia Domari or Loma (+ introduction into exonyms/ethnic slurs Zott, Koli, Tsigan & Gypsy)

The origin of the name Roma, Domari & Loma

In a part of South Asia historically known as Bharat (nowadays India, Pakistan, Nepal & Bangladesh) exists a group of people called the Domba or Dom (which is either ethnic group or caste umbrella of various jatis within Śudra varna), in Sanskrit known as ḍoma (pronounced as Roma, with retroflexed R, which in some Romani dialects survives till present).

The Domba/Dom are mostly nomadic group, but exists settled down communities, most of them are of Śudra varna and very few of them are Dalits.

The Dom are among other things musicians, blacksmiths, snake-leaders and acrobats. Which corresponds with traditional Romani jobs.

Its presumed root, ḍom, which is connected with drumming, is linked to damara and damaru, Sanskrit terms for "drum" and the Sanskrit verbal root डम् ḍam- 'to sound (as a drum)', perhaps a loan from Dravidian, e.g. Kannada ḍamāra 'a pair of kettle-drums', and Telugu ṭamaṭama 'a drum, tomtom'.

Not only name corresponds with the origin from the Domba but also genetical results of all the Roma from Europe, including myself.

Notes:

Jati determines what is your traditional profession according to Indian caste system. If you're born into jati of musicians, you'll be musician and your offspring too.

Varna - literally means "colour" but it is rather social class system originating in Ancient India's Brahmanism dividing Indian society into four varnas. The Brahmins (priests), Kshatriyas (rulers & warriors), Vaishyas (traders) and Śudras (workers). These four are called Savarna. Those who are outside are Avarna, also known as Dalits (also known as untouchables).

Due to sound changes which occurred other people of this group call themselves Domari or Loma and didn't left at same time as the Roma.

Exonyms

Zott - This exonym comes from Persian/Arabic mispronounciation of the ethnic name of the Jatt People from India.

(Wikipedia) The Jatt are a community of traditionally non-elite peasants and herders in Northern India and Pakistan.Originally pastoralists in the lower Indus-valley of Sindh, Jats migrated north into Punjab in late medieval times, and subsequently into Delhi and northeastern Rajputana, and the western part of nowadays Uttar Pradesh in the 17th and 18th centuries.

According to genetical results of various Roma of various Romani tribes, I've seen (including me). All our people have Jatts in results, as population we come from.

Extra information. Around 800 AD when the Umayyad Caliphate fell and Abbasid Caliphate was not fully consolidated yet, the Roma (with various local Mon-Muslim people) tried to establish the Zottistan in nowadays Iraq. Unfortunately this uprising of Non-Muslims was crushed, the Roma were send part to Byzantine Empire's borders and part (probably men) inprisoned in Syria from where were liberated by the Byzantines.

Koli/Kowli - Another exononym used in Iran and Iraq, probably connected with the Kol People of India.

(Wikipedia) The Kol people are a tribe in north-east of India within Gangetic Plain and Madhya Pradesh, who migrated there from Chota Nagpur in central India around five centuries ago. Mostly landless and dependent on forest produce to make a living, they are Hindus and are designated as a Sheduled Caste. It is the third most commonly found tribe in Madhya Pradesh. The Kol of the Kharwar Munda group is an ancient tribe. the Kol reside in open spaces and tell they're in relationship with Shabari (a devotee of Ram). The Kol is fond of music and many instruments are found in their houses. They do not eat cow's and lion's meat and do not believe in totam vad (tona-totka, etc.) The "kol dehka" is their ancient primitive dance. The panchayat of kolo is called muqaddam, whose head is called 'gohiya or gotiya'.

According to genetical results of various Roma of various tribes, I've seen (including me), we all have the Kol in results.

Tsigani/Cigani/Tsígganoi - This exonym comes from the Byzantine Empire and is based on confusion.

The Byzantines confused us with the Áthínganoi (ἀτσίγγανοι - in nowadays pronounciation of Greek it is Átsígganoi), the religious group of (formerly?) Manicheans from Persia, who didn't wanted anyone to touch them, which is the meaning of that name "don't touch" (a = not, thíngete = touch). They were darker than Anatolians & Greeks and they used to eat from the ground (not any source mentions plates or so, which for the Roma would be ritually unclean if not plates were placed under food). The Áthínganoi came in 600 AD, which means before our arrival. The Áthínganoi were seen as "Judaising heretics" and probably either killed or turned into mainstream Christianity literally shortly before our arrival.

Notes:

The Áthínganoi may be either other Indic people who were a part of some predecessing migration wave (there were waves of various castes before and after us towards the West) or some sort of Iranians or Arabs. Or maybe Manichean missionaries.

The Roma probably also didn't wanted to be touched by the outsiders, as ritually they (outsiders) might be unclean to them. Which in many examples is still a thing.

Gypsies/Gýftoi/Gyoúftoi/Gyupti/Farahúni/Pháraó Népe/Gitanos - Another originally Byzantine and later various origin exonym.

Originates in a believe that the Roma arrived from Egypt, which the Roma alone suggested, as they had stories for European Christians to be accepted as repentant pilgrims.

The Roma claimed that they came to Palestina from Egypt to forge a nail for the crucifixion of Jesus Christ. And for that they started live like repentant pilgrims.

Also huge Roma tent "cities" (first original eastward from Constantinople and second/later one nearby city of Methoni - about others I did not found informations) used to be called "Small Egypt". This collective memory about the "Small Egypt" survived few Centuries, so when the Roma were asked from where they came, they answered from Egypt.
