Bengali-Sanskrit Lineage Map: Cognate Blueprint & Phonetic Shift Explorer

Cognate Lexicon

5 Core Roots

Cognate Evolution: সূর্য / सूर्य

Tatsama Blueprint

1. Classical Sanskrit

सूर्य (sūrya)

IPA: [suːɾjɐ]

Vedic root svar (heaven/light), formal Devanagari orthography.

2. Magadhi Prakrit / Abahatta*sūriya
IPA: [suːɾijɐ]
Epenthesis inserted to simplify cluster -ry- before regional re-borrowing.

3. Modern Bengali

সূর্য (shurjo)

IPA: [ʃurd͡ʒo]

Tatsama spell-rule: sibilant shifts to [ʃ], cluster -ry- geminates as [rd͡ʒ].

Phonetic Transition Mechanism

Preserved orthography with phonetic shift: Sanskrit [s]→Bengali [ʃ], semivowel cluster [rj] geminates to [rd͡ʒ].

Simulate Acoustic Transition: Sanskrit [suːɾjɐ] → Bengali [ʃurd͡ʒo]

Historical Indo-Aryan Branching & Epochs

Scrub through time to trace why Bengali retains >50% direct Sanskrit vocabulary.

Epoch: 1500 BCE

1500 BCE Present

Vedic Sanskrit

c. 1500 – 600 BCE

The earliest Old Indo-Aryan ancestor with full pitch accent, 8 case forms, dual number, and strict vocalic r (ṛ). Bengali retains exact liturgical lexical items and grammatical inflections directly descended from this root stock.

Syntactic & Morphological Parallels

Linguistic Dimension	Classical Sanskrit	Modern Bengali	Why Native Bengali Speakers Excel
Lexical Stock (Vocabulary)	100% Root Forms (Dhatus)	>55% Tatsama (Identical) + 30% Tadbhav (Prakrit Sound Shift)	Bengali formal prose (Sadhu and Cholit) incorporates pure Sanskrit stems with zero foreign semantic distortion.
Dual Number (Dvivachana)	Singular, Dual, Plural (एकवचन, द्विवचन, बहुवचन)	Merged into Singular vs. Plural (একবচন, বহুবচন)	Loss of dual simplifies learning: Bengali speakers easily internalize dual as a paired subset of standard plural declensions.
Case Systems (Vibhaktis)	8 synthetic synthetic cases marked on noun stems	Analytical case endings & postpositions (যেমন -এর, -কে, -তে) derived from Sanskrit	Bengali genitive -er traces to Prakrit -kera (Sanskrit kṛta); locative -te traces to Sanskrit sthitē.
Sibilants & Consonant Clusters	Distinct dental (s), retroflex (ṣ), palatal (ś)	Unified acoustic realization [ʃ], distinct script orthography preserved	Because Bengali preserves the original Devanagari 3-sibilant spellings (শ, ষ, স), reading Classical Sanskrit is intuitive.
Contrast with Dravidian Languages	Indo-Aryan inflectional syntax, non-agglutinative root core	Direct Eastern Indo-Aryan sister language	Tamil/Telugu operate on distinct Dravidian agglutinative root stocks; Bengali shares Sanskrit's underlying genetic etymons.
