It was first reported to be a separate language by Lionel Bender in 1977,[2] based on data gathered by missionary Harvey Hoekstra. A grammar was published in 2015 (Kibebe 2015). Some early treatments classified it as a Nilo-Saharan language (Anbessa & Unseth 1989, Fleming 1991, Blench 2010), but more recent investigation (Kibebe 2015) found none of the grammatical features typical of Nilo-Saharan, and showed that the Nilo-Saharan vocabulary items are loans from Surmic languages (Dimmendaal to appear, Blench 2019).
As they shift from hunting and gathering to more settled agriculture and to working as laborers, many of its speakers are shifting to other neighboring languages, in particular Majang and Shekkacho (Mocha); its vocabulary is heavily influenced by loanwords from both these languages, particularly Majang, as well as Amharic.
Classification
Once the many loanwords from its immediate neighbors, Majang and Shakicho, are removed, the wordlists collected show a significant number of Koman words side by side with a larger number of words with no obvious external relationships. The tentative grammar so far collected offers few obviously convincing external similarities. On this basis, Fleming (1991) has classified Shabo as Nilo-Saharan and, within Nilo-Saharan, as nearest to Koman. Anbessa & Unseth consider it Nilo-Saharan, but present little by way of argument for their position, and no detail on its position within the family. Schnoebelen (2009) in his phylogenetic analysis says that Shabo is best treated as an isolate, but does not exclude the possibility of contradicting evidence gained from applying the comparative method (which still needs to be done); Kibebe (2015) evaluates Schnoebelen as the most rigorous comparison to date. Blench (2010) maintains that Shabo does pattern with the Nilo-Saharan family, and that recent data on Gumuz helped tie the languages together. More recently, Blench (2019) classifies Shabo (Chabu) as a language isolate, noting little evidence for it being part of Nilo-Saharan.[3]
Blench (2017) lists the following similarities among Shabo, Gumuz, and Koman lexical forms.[4]

The comparison with reconstructed languages of the Surmic and Koman branch as well as three languages from the Gumuz branch shows slight phonological similarity for the first person singular of Proto-Southwest Surmic and the probable ancestor of the Gumuz languages but additional information is lacking and, otherwise, so far it does not seem very approximate.
[s] and [ʃ], and sometimes also [c],[ɟ], and [ʒ], are in free variation, as in Majang; Teferra speculatively links this to the traditional practice of removing the lower incisors of men.
[h] and [k] occasionally alternate.
Implosive consonants are common in languages of the area, but ejective consonants are not found in Majang.
Consonant length is found in several words, such as walla "goat", kutti "knee"; however, it is often unstable.
Teferra tentatively postulates 9 vowels: /i//ɨ//u//e//ə//o//ɛ//a//ɔ/, possibly with further distinctions based on advanced tongue root. Five of these, /a//e//i//o//u/, have long counterparts. Occasionally final vowels are deleted, shortening medial vowels: e.g. deego or deg "crocodile".
The syllable structure is (C)V(C); all consonants except /pʼ/ and /tʼ/ can occur syllable-finally.
The language is tonal, but its tonology is unclear. Two minimal pairs are cited by Teferra 1995, including há "kill" versus hà "meat".
Shabo has an unusually complex pronoun system for Africa:[5]
Singular
Dual
Plural
1st person
masc.
tiŋŋ, ta, ti
antʃ
jiŋŋ
fem.
ta
ann
jaŋfu
2nd person
masc.
kukk
tʃitʃak
sitalak, silak
fem.
kuŋg
sijak
subak
3rd person
masc.
ji
otʃtʃa
odda
fem.
oŋŋa
ojja
otala
The pronouns "I" and "he" have been compared to Surmic languages; however, there are also resemblances in the pronouns with the Gumuz languages (Bender 1983). The gender distinctions made are unusual for Africa.
Verbs
Negation is by adding the particle be after the verb or noun negated: gumu be "(it is) not (a) stick", ʔam be-gea "he will not come" ("come not-?"). Negative forms in b are widespread in Nilo-Saharan and Afro-Asiatic languages.
There appears to be a causative suffix -ka: mawo hoop "water boiled" → upa mawo hoop-ka "(a) man boiled water".
A particle git (infinitive? subjunctive?) marks the verb in constructions with "want": moopa git inɗeet ("sit git want") "I want to sit".
Much of the verbal morphology is uncertain; there appears to be a 3rd person singular future suffix -g- (e.g. inɗage t'a-g "he will eat") and a 2nd person plural suffix -ɗe
subuk
you-PL
maakɛle
corn
kak
PAST?
t'a-ɗe
eat-2PL
subuk maakɛle kak t'a-ɗe
you-PL corn PAST? eat-2PL
"You (pl.) ate corn"
Nouns
Plurals are optional; when used, they are formed with a word yɛɛro afterwards.
There is a suffix -ka which sometimes mark the direct object, e.g. upa kaan-ik ye "a man saw a dog" ("man dog saw"), but also has many other uses. A similar suffix is found in many Eastern Sudanic languages, but there it is specifically accusative.
Postpositions
Shabo uses postpositions after nouns, e.g.: upa mana pond ɗɛpik moi "a man sat on a rock" (lit. "man rock on ? sat").
