A few folks from Madras Presidency had moved to erstwhile East Pakistan before the Partition. A few of them settled in Dhaka whom still speak Telugu, although, there is another, distinct, community who are known as "Madrasi" or "Madraji". All speakers seem to employ "Naidu" surname. There around 2,000 families in Bangladesh, mostly (if not all) whom are in Moulvibazar, Sylhet (close to the border with Barak Valley, Northeast India) as it seems to me. Language is oral only, although the educated folks employ Bengali script for it. While they do seem to call their language as "Telugu", it is described as a creole of Tamil and Telugu, although as a native Tamil speaker i struggle to find any resemblence of Tamil. I shall post my observations here, as it seems no one knows much about this language and hence no notings on how it differs from Standard Telugu.
English:I forgot how long I haven't been travelling.
Madraji:
Normal transliteration:
nanu cēna roili beṭṭi teraganaki yāl̄edu adi nāno maric pan
IPA:
/nanu t͡ʃəːna ɾɔi̯li beʈːi t̪eɾagʌnaki i̯alːedu adi nano maɾit͡ʃ pən/
Telugu script:
నను చేనా రొయిలి బెట్టి తెరగనకి యాల్లేడు అది నానో మరిచ్ పన్
Standard Telugu:
Normal transliteration:
nēnu cālā rōjulu veḷḷi tiragaḍāniki kālēdu, adi nāku maricipōyindi
IPA:
/neːnu t͡ʃaːla roːd͡ʒulu veɭːi t̪iraɡaɖaːniki kaːleːdu adi naːku maɾit͡ʃipoːjindi/
Telugu script:
నేను చాలా రోజులు వెళ్లి తిరగడానికి కాలేదు, అది నాకు మరిచిపోయింది.
Here, the pronoun nēnu appears as nanu (Same as Kannada!), with /eː/ becoming /a/. This also occurs in /mamʊ/ [mamu if thee does not know IPA] (corresponds to Standard mēmu meaning "we"). Cālā “much” appears as cəːna, showing a different vowel quality and possibly /l/ > /n/. Rōjulu "days" appears as ɾɔi̯li, with a diphthongal vowel and changes to the medial consonant and final vowel. Particularly notable is veḷḷi "going/having gone", which appears as beʈːi, involving /v/ > /b/ and /ɭː/ > /ʈː/. The Standard Telugu tiragaḍāniki corresponds to t̪eɾagʌnaki, showing both phonological changes and a differently shaped stem, although the final -naki/-niki suggests related grammatical morphology. The form i̯alːedu appears to contain a counterpart of Standard Telugu lēdu "is not", but its exact structure is uncertain. In contrast, adi "that/it" is essentially identical in both varieties. The final maɾit͡ʃ pən is broadly comparable to maricipōyindi "was forgotten", but appears to use a substantially different verbal construction.
English: How many of you do not agree to go to that place?
Madraji:
IPA:
/mɪlu ɔu̯lu lɔʷakʌɾ kælːaki ɾad͡ʒi ledu/
Normal transliteration:
milu aulu lōwakar keḷḷaki rāji lēdu
Telugu script:
మిలు ఔలు లోవకర్ కెళ్ళకి రాజి లేదు
Standard Telugu:
IPA:
/miːloː ent̪amand̪i aː prad̪eːɕaːnɪki veɭːaɖaːnɪki raːd͡ʒiːɡaː leːɾu/
Normal transliteration:
mīlō entamandi ā pradēśāniki veḷḷaḍāniki rājīgā lēru?
Telugu script:
మీ లో ఎంతమంది ఆ ప్రదేశానికి వెళ్లడానికి రాజీగా లేరు?
/mɪlu/ corresponds broadly to mīlō, with /iː/ shortened and the final vowel different. /ɔu̯lu/ does not transparently correspond to Standard entamandi, suggesting either a different lexical item or a heavily reduced construction rather than ordinary sound change. Likewise, /lɔʷakʌɾ/ is not a straightforward phonological equivalent of ā pradēśāniki and contains the unusual labialized /lʷ/. /kælːaki/ is more suggestive of a counterpart to veḷḷaḍāniki, with a major change in the stem and the conspicuous [æ] vowel, although the shared -ki points to related grammatical function. The final /ɾad͡ʒi ledu/ is the most readily recognizable part: rāji lēdu "there is no agreement," though Standard Telugu in this exact sentence would more naturally have rājīgā lēru.
English: Will you take parboiled rice or sunned rice?
Madraji:
Normal transliteration:
uppir bim tiskōtayo nā pecchi bimu(?)
IPA:
/upːɪɾ bim tiskɔt̪aʲo na pet͡ʃːɪ bimʊ/
Telugu script:
ఉప్పిర్ బిమ్ తిస్కోటయో నా పెచ్చి బిము?(?)
Standard Telugu:
Normal transliteration:
uppuḍu biyyaṁ tīsukuṇṭāvō lēka eṇḍabeṭṭina biyyaṁō?
IPA:
/upːuɖu bijːã t̪iːsukuɳʈaːvoː leːka eɳɖabeʈːina bijːamoː/
Telugu script:
ఉప్పుడు బియ్యం తీసుకుంటావో లేక ఎండబెట్టిన బియ్యమో?
/upːɪɾ/ is apparently related to the word for parboiled rice, although it does not correspond straightforwardly to Standard uppuḍu. The borrowed noun /bim/ is particularly notable: the expected Standard Telugu word is biyyaṁ "rice," so the Madraji form has a markedly different shape, suggesting lexical replacement or strong sound change rather than ordinary pronunciation variation. /tiskɔt̪aʲo/ is recognizably close to Standard tīsukuṇṭāvō "will you take," retaining the tisk- / tīsuk- verbal element and the interrogative -ō, but with substantial reduction of the middle morphology and a different vowel/consonant pattern. The second option, /na pet͡ʃːɪ bimʊ/, appears to correspond to "or sunned rice," but its exact segmentation is uncertain; /na/ may be an alternative-marker corresponding functionally to Standard lēka, while /pet͡ʃːɪ/ could encode the preparation/process.
English: At that moment you had a fever and stomach ache, that is why you couldn't go
Madraji:
IPA:
/ɔpːunːiku oʷaʂ͡ʈmu koɾupnopːu unɖidi əndɛkɛ əlːepɔnao̯/
Normal transliteration:
oppunnikū owaṣṭmu korupnoppu uṇḍidi endeke allepōnāo̯
Telugu script:
ఒప్పున్నికు ఓవష్ట్ము కొరుప్నొప్పు ఉండిది ఎందెకె అల్లెపోనాఓ(?)
Standard Telugu:
IPA:
/aː samajaːniki niːku d͡ʒʋaɾam kaɖupunopːi uɳɖeːd̪i and̪ukeː veɭːaleːkapoːjaːʋu/
Normal transliteration:
ā samayaniki nīku jvaraṁ, kaḍupunoppi uṇḍēdi, andukē veḷḷalēkapōyāvu.
Telugu script:
ఆ సమయంలో నీకు జ్వరం, కడుపునొప్పి ఉండేది, అందుకే వెళ్లలేకపోయావు.
/ɔpːunːiku/ appears to correspond to Standard Telugu ā samayaniki "at that time" although the correspondence is not transparently phonological and may involve a different lexical expression. /oʷaʂ͡ʈmu/ is plausibly the equivalent of jvaraṁ "fever" but the form is substantially different, including the unusual rounded /oʷ/ and the affricate-like /ʂ͡ʈ/ sequence. The expression /koɾupnopːu/ is much more recognizably related to kaḍupunoppi "stomach ache": both contain a -noppi element, but Madraji has major changes in the initial portion and consonant pattern. /unɖidi/ corresponds closely in function to uṇḍēdi "was/would be" preserving the characteristic Telugu uṇḍ- "be/remain" verb while changing the vowel and ending. The causal expression /əndɛkɛ/ is especially suggestive of Standard andukē "that is why" with the same broad andu-/ande- + kē structure but a very different phonetic realization. Finally, /əlːepɔnao̯/ appears to correspond to veḷḷalēkapōyāvu "you could not go," but is heavily reduced and remodeled; notably, the Madraji form still seems to contain material corresponding to lēka-pō-, suggesting that the Telugu inability + motion verb construction may be retained despite substantial phonological reduction.

About numerals, ditīyo, tritīyo, cōturtho, these forms are very different from ordinary colloquial Standard Telugu numerals, which use the Dravidian ordinal series reṇḍava/reṇḍō, mūḍava/mūḍō, and nālugava/nālugō. Madraji instead has forms such as /ditiːjɔ/ and /tɾitiːjɔ/, which are strikingly close to the Sanskritic ordinal forms dvitīya "second" and tṛtīya "third" but with a highly simplified phonetic shape and final -yō/-jɔ. The fourth, /t͡ʃʰoturt̪ʰo/, similarly corresponds to Sanskrit caturtha and is much closer to a Sanskrit-derived ordinal than to Standard Telugu nālugō. Thus, this may not simply be a case of Madraji preserving an old Telugu form: it appears to have reorganized the ordinal system around Sanskrit-derived forms.
There is also a very noticeable Eastern Indo-Aryan contact resemblance here. Bengali দ্বিতীয় is dvitīẏo and তৃতীয় is tṛtīẏo, so the Madraji /ditiːjɔ/ and /tɾitiːjɔ/ have essentially the same overall phonological shape: d/t + itī + yō and tritī + yō. The Bengali endings are particularly close to Madraji -jɔ/-yō. The fourth, Bengali চতুর্থ côturtho, is also strikingly similar in overall shape to Madraji /t͡ʃʰoturt̪ʰo/. Sylheti, being another Eastern Indo-Aryan language, also has closely related Sanskrit-derived ordinal forms. So, unlike the earlier examples where Bengali influence was not especially obvious, this particular set shows a quite conspicuous parallel with Bengali/Sylheti.
Perhaps all of these forms ultimately go back to Sanskrit dvitīya, tṛtīya, caturtha, and Sanskrit-derived ordinals could have entered Madraji independently through Telugu's own extensive Sanskrit vocabulary. But the phonetic shapes /ditiːjɔ/, /tɾitiːjɔ/, /t͡ʃʰoturt̪ʰo/ happen to line up unusually well with the Eastern Indo-Aryan forms, so this is something worth checking across the rest of the Madraji corpus.
