Shilluk (natively Dhøg Cøllø, ) is a language spoken by the Shilluk people of South Sudan. It is closely related to other Luo languages. The term Shilluk is a pronunciation of Arabic origin.

Phonology

Vowels

Each of these vowels also exists in a long form and an overlong form which are phonemic.

Advanced and retracted tongue root

Shilluk, like most Nilotic languages, differentiates vowels according to their place of articulation. They are either pronounced with advancement of the root of the tongue or with retraction of the root of the tongue. Gilley uses the terms "extended larynx" or "blown vowel". The vowels with advancement of the root of the tongue are, , , , and their corresponding long variants. The vowels with retraction of the root of the language are denoted by a macron below the letter:, , , , and and their corresponding long variants.

Consonants

Tone

Shilluk has a rich inventory of tones, with at least seven distinctive tone patterns or tonemes. There are three level tonemes: Low, Mid and High. In addition, there are four contours – the Rise and three falling configurations: Fall, High Fall and Late Fall. These are denoted by the following diacritics:

Syllable structure

Uninflected native stem syllables are overwhelmingly monosyllabic. With few exceptions, these monosyllabic stems typically consist of an onset, a vowel (nucleus), and a coda. Their structure is: C(Cj/w)V(V)(V)C.

Grammar

Morphology

Monosyllabic stems give rise to polysyllabic words through processes of derivation or inflection. For verbs and nouns alike, the most common prefixes are /a- ʊ-/, and the most common suffixes are /-Cɪ -ɪ -a (-ɔ)/. Further, alternations of vowel length and tone play an important part in inflectional morphology.

Verbs

Transitive verb classes

Shilluk transitive verbs have a phonological root that consists of a single closed syllable of the form /C(j/w)V(V)C/. "That is, the root vowel is either short or long, and clustering of consonants is restricted to the onset, where either of the semivowels /w,j/ may follow another consonant." There are seven classes distinguished by alternations in terms of vowel length and tone. These differences are illustrated by subject-voice past, past second-person singular, and object-voice imperfective in the table below.

Nouns

Noun inflection is characterized by head marking: pretensive and construct-state are both inflections that mark the head, not the dependent. For example, English has a person's rodent, where the head is rodent, and the possessive marking is on the dependent person's. In contrast, Shilluk has a pretensive affix on the head (e.g., dúup = "rodent", dû́uup = "rodent belonging to"). Number is marked, but no predictable system has been identified. Instead, there are over 140 different patterns of number marking on nouns. Numerals in Shilluk are nouns.

Orthography

A Latin alphabet was developed for Shilluk by Christian missionaries in the early 20th century. There are 29 characters in Shilluk orthography; 10 vowels and 19 consonants.

Oral literature

In 1912, Diedrich Westermann published The Shilluk People, their Language and Folklore, which contains a wide selection of texts in the Shilluk language with English translations; there are 61 tales in addition to prayers, songs and riddles. The book also contains a Shilluk grammar. Here are some of the riddles: For a selection of over 200 Shilluk proverbs and riddles with German translations, see ''Die Schilluk. Geschichte, Religion und Leben eines Niloten-stammes'' by Wilhelm Hofmayr. This book also contains songs in Shilluk, and some of the songs have an accompanying musical transcription.
