The Telugu spoken in these two deltas is the base on which the modern written and broadcast standard was built, which gives it an unusual property: its speakers rarely think of themselves as having an accent. Inside the region there are still clear varieties — a Godavari register famous for its politeness particles and its willingness to lengthen a sentence, a flatter and faster Krishna–Guntur register, and a Nellore variety with real Tamil contact — but the differences are lexical and prosodic rather than grammatical. The nineteenth-century argument over whether to write grandhika, the classical register, or vyavaharika, the spoken one, was fought largely by men from this coast and the delta's speech is what won.
Godavari TeluguDravidian, South-Central
The Konaseema and Rajahmundry register, marked by heavy use of the respectful andi and by a characteristically unhurried sentence. It is the variety Telugu cinema uses when it wants a character to sound gracious.
Krishna–Guntur TeluguDravidian, South-Central
Flatter, faster and closest to what is heard on television news. This is the register the literary standard was codified from, which is why it reads as neutral rather than as regional.
Nellore TeluguDravidian, South-Central
The southern coast, with Tamil-contact vocabulary and a distinct set of verb endings, shading further into Tamil around Pulicat where households have run both languages for generations.
Delta fishing-community speechDravidian, South-Central
A separate occupational vocabulary — for winds, tides, net types, catch grades and boat parts — that does not appear in a dictionary and is not shared with the farming villages a kilometre inland.
Deccani Urdu in the port townsIndo-Aryan, Hindustani
Long-settled Urdu-speaking households in Machilipatnam, Guntur, Eluru and Nellore, a residue of the Golconda and Nizam-period administration and of the export trade.
