TheGtaʼ language (alsoGataʼ,Gataʔ, andGtaʔ), also known asGta Asa,Didei orDidayi ([ɖiɖaːj(i)]), is anAustroasiatic language spoken by theDidayi people of southernmostOdisha in India. It is notable for itssesquisyllabic phonology^[3] andvigesimal (base 20) numeral system.

The Gtaʼ language belongs to the South Munda subgroup of theMunda branch of theAustroasiatic language family.^[1] Within South Munda, Gtaʼ is generally considered to be the first branch off a node that also subsumes theRemo andGutob languages; this subgroup of South Munda is known as Gutob–Remo–Gataq. It is phonologically and morphologically divergent within that branch.^[4]

Gtaʼ has two main varieties, namely Plains Gtaʼ and Hill Gtaʼ.

Gtaʼ echo-formation shows some striking similarities with echo-formation in neighboring Munda languages such as Remo and Gorum as well as in theDesia dialect ofOriya spoken in the Koraput Munda region. The most conspicuous feature they have in common with Gtaʼ is that echo-words in all three of these languages are also derived from base words by changes in the vowels alone.^[5]

Gtaʼ is spoken by 3,000 people primarily inMalkangiri district,Odisha as well as adjoining areas ofKoraput district.^[3] According to Anderson (2008), it is spoken by less than 4,500 people.

Ethnologue reports the following locations:

• Odisha (47 villages): Kudumulgumma block and Chitrakonda block ofKoraput district andMalkangiri district, south of Bondo Hills; some in Khairput block
• East Godavari district,Andhra Pradesh

Gtaʼ has the 5 canonical vowels /a, e, i, o, u/, and sometimes a sixth vowel /æ/. To this can be added several nasalized counterparts: /ã, õ, ũ/ and sometimes /ĩ/. Gtaʼ has the following consonants:^[3]

There are numerous lexical items that contain initialconsonant clusters and CCVC word shape in Gtaʔ. Eg.plwesa ('jackfruit),gtaʔ ('Gtaʔ person').

Nouns in Gtaʼ are primarily marked for case, number and possession.^[6]

Nouns also have two forms, one a free full form, the other a bound short form. These latter occur only when the noun is compounded with another noun or a verb for derivational purposes, and are hence labeled "combining forms". The combining form usually involves removing an affix or shortening the noun in some way.

LikeKharia,Gutob andRemo, Gta verbs only index the S and A arguments.

S-V-O transitive configuration has been fossilized with only one survived example: the plural marker-har is used to indicate 1>3 scenario.

Gtaʔ is also notable for its use ofecho words. There are four broad categories of echo forms:^[5]

• a-forms, indicating gross variety;
• i-forms, indicating diminutive or tender variety;
• u/a-forms, indicating variety different from a related category;
• partially changed forms, indicating inferior variety: a-forms, indicating grossness; and i-forms, indicating tenderness.

The phonological rules for deriving one type of echo word are as follows:^[5]

1. Echo-words are formed by changing only the vowels of the base word.
2. The echo-word must differ from the base word. The vowel of univocalic base words is reflected as either /a/ or /i/ in the echo-word. For base-word /u, e, o/ the vowel /a/ is preferred, while for base word /ɛ/ the vowel /i/ is preferred.
3. The vowels of disyllabic base words are reflected in the echo-word as follows:
   • Both vowels are reflected as either /a/ or /i/; or
   • Only one of the base-word vowels is reflected as /a/ or /i/ while the other is reflected unchanged; or
   • The first vowel (V1) changes to /u/ while the second (V2) changes to /a/.
4. In the case of trisyllabic base words, one, two or all three of the vowels (in adjacent syllables) are reflected as either /a/ or /i/.
5. The echo-forms of compound words, irrespective of their vocalic structure, are derived as follows:
   • In the case of compound verbs consisting of two verb stems, one or both stems undergo change, depending on their relationship with each other;
   • Nominal combining forms occurring with verb stems change independently; those attached to noun stems change only at par with the main stem.
   • In verbal constructions incorporating a prefix, both the prefix and the stem change as a unit.

Combining forms of nouns occurring with verb stems can be echoed independently of the verb stems; those occurring with noun stems either remain intact or change at par with the main stems.

Gtaʔ has two switch reference markers,tʃe (same subject) andla (different subject) to link the finite verb of the preceding clause with the non-finite verb of the following clause. This system reflects in Gtaʔ narrative style of oral folk stories.^[7]

Gta' numeral system isvigesimal.^[8]
