Kurukh phonology

The phonology of Kurukh (also spelled as Kurux or Oraon), a North Dravidian language spoken by the Kurukh (Oraon) and Kisan people of East India, consists of a six-to-eleven vowel system with short and long pairs, along with a consonant inventory that separates dental and retroflex sounds. A clear identifying feature of the language within the North Dravidian branch is the sound change that created the voiceless velar fricative /x/. This phonetic breakdown is based on the historical work of Martin Pfeiffer (1972), alongside early data from Pinnow (1964) and Grignard (1924).

Vowels

Kurukh uses between six and eleven vowel sounds. The first table is the one given by Pfeiffer (1972), and the second one is given by Lakra and Rahman (2016).

Vowels

	Front		Central		Back
	short	long	short	long	short	long
Close	i	iː			u	uː
Mid	e	eː	ə	əː	o	oː
Open			a	aː

Pfeiffer notes that long vowels are to interpreted as a sequence of two short ones. He adds that, while a previous researcher asserts that /ə:/ does not exist, it is found in at least eight words, and that /a:/ becomes /ə:/ in the past tense. Nasalization is also common for most vowels (like /ã/ or /ĩ/), but historically it does not happen with the schwa.

+ Vowels

	Front		Central		Back

Close	ɪ	iː			ʊ	uː
Mid	e	eː	ə
Open	a		ʌ		ɒ	ɑː

Consonants

The native consonant sounds match standard Dravidian family lines, though some liquid sounds like laterals have merged over time.

Consonants

	Bilabial		Dental/Alveolar		Retroflex		Postalveolar / Palatal		Velar		Glottal
Nasal		m		n		(ɳ)		ɲ		ŋ
Stop / Affricate	p	b	t	d	ʈ	ɖ	t͡ɕ ~ t͡ʃ	d͡ʑ ~ d͡ʒ	k	ɡ	ʔ
Fricative									x		h
Sibilant			s
Trill / Flap				r		(ɽ)
Approximant		w		l				j

The velar fricative /x/ comes from the original Proto-Dravidian stop /*k-/ under certain sound environments. In daily speech, this sound naturally changes to a uvular fricative [χ] whenever it is pronounced next to back vowels like /u/ or /o/.

The retroflex nasal [ɳ] is not a separate independent sound; it is an allophone that only appears when placed right before other retroflex stops. Also, while aspirated sounds are common in the vocabulary, they only appear in words borrowed from Indo-Aryan languages and are not part of the original core Dravidian roots.

Phonotactics

Native Kurukh roots only allow double (geminate) consonants right after short vowels, like in the word palla ('tooth'). Roots that have a long vowel are normally followed by single consonants.

Extra vowels are often added to break up difficult consonant clusters at the end of a root word, which creates forms like xeexᵉl ('earth'). These extra helper vowels naturally drop out whenever a suffix starting with a vowel is added, which can be seen in the accusative form xeexl-an.
