Tommo So is a language spoken in the eastern part of Mali's Mopti Region. It is placed under the Dogon language family, a subfamily of the Niger-Congo language family.

There are approximately 60,000 speakers of Tommo So. Of the twelve Dogon languages, it is the second-most common. It is classed as a 6a (vigorous) language under Ethnologue's language status classifications—the language is "used for face-to-face communication by all generations and the situation is sustainable." Children are still acquiring Tommo So as their first language. Bambara and French (Mali's lingua franca and national language) are common second languages for Tommo So speakers, with the former being common among those that have spent time in other areas of Mali, and the latter being used to communicate in the classroom or with foreigners.

Phonology

Vowels

Tommo So contains 17 vowel phonemes. There are seven basic vowels spanning four vowel heights and three vowel backnesses.

Besides the 7 basic vowels, Tommo So's vowel inventory includes their long counterparts and 3 nasalized long vowels. The placement of vowels in words does not affect their length—long vowels tend to be about 138ms long, and short vowels tend to be about 67 ms long. The nasalized vowels /iː/ and /uː/ are present in the language but occur infrequently and irregularly, and are not considered phonemic.

Consonants

Tommo So contains 17 consonants. There are 5 places and 6 manners of articulation. Consonant length is contrastive—for example, and are considered to be different words—the first means 'look for', and the second means 'spend the day'.

The consonant inventory includes the alveolo-palatal affricate —the consonant does not appear by itself. There are a few other consonants sounds that occur in consonant speech (such as and ). However, these sounds occur only in ideophones, and are not considered part of Tommo So's consonant inventory.

Syllabic structure

There are eight syllable types in Tommo So: (C)V, (C)Vː (C)VR, (C)VC, N, NCV, NCVː, and CVV. N represents a nasal consonant, and R represents a sonorant. A (C)VC syllable must be followed by an onset identical to this coda. Some examples of these syllable structures are provided below.

Tone

Tone is significant both lexically and grammatically. Tommo So contains two tones, high (H) and low (L). Based on an analysis of recorded words, the distribution and placement of H and L tones seem to be governed by a set of patterns that are relatively unpredictable for nouns, numerals, and adjectives, and predictable for verbs.

Lexical Tone

Almost all syllables have an associated H or L tone, and every stem must contain at least one H tone. Although tones are contrastive, there are very few minimal pairs that are only tonally distinctive. A few examples are listed below.

Grammatical Tone

Tommo So, like other Dogon languages, uses tonal overlays. A stem's tones are overwritten by a pre-determined tone overlay depending on the context in which the stem appears. Verb phrases' tones are replaced based on inflectional morphology, and only affect the verb stem. As an example, main clauses' affirmative imperfect overlay is {HL}, and their negative imperfect overlay is {L}. Relative clauses' affirmative imperfect overlay does not change tones, and their negative imperfect overlay is {L}. Given the noun stem ('run') of the /LH/ tone class, conjugation would result in the following.

Noun phrases' tones are replaced based on the relationship between words in the noun phrase, and can affect multiple words. Although verb phrase tonal overlays are strictly defined for all verbs, noun phrase tonal overlays are dependent on the object in the noun phrase being possessed or not.

Morphology

Tommo So is an agglutinative language. In general, when these morphemes are attached to each other, they retain their original form and meaning within the new word. Tommo So's morphology contains affixation, clitics, reduplication, and compounding.

Affixation

As an agglutinative language, the affixation of morphemes plays a major role in Tommo So's morphology. Almost all of the language's bound morphemes are used as suffixes—prefixes are only seen in the form of reduplication, when used for deadjectival nominalization.

Tommo So contains five verbal derivational suffixes, listed below.

FACT:factitive REV:reversive MP:mediopassive

There are some cases in which the 'reversive' suffix -ílɛ́ does not seem to contain a reversive meaning. For example, the word yàmá means 'be ruined', but the word 'yàm-ílɛ́' means 'ruin.' Some derivational suffixes just happen to carry "no discernable meaning at all."

Tommo So does not contain much nominal morphology—the only two meaningful suffix types that attach to nouns are those that implement a human/non-human system and the diminutive suffix -ý. In the case below, íí is an allomorph of -ý.

yàá-m=mbe

female-HUM.PL=PL

yàá-m=mbe

female-HUM.PL=PL

'women'

ɛ́njɛ́

chicken

íí

DIM

ɛ́njɛ́ íí

chicken DIM

'chick'

Clitics

There are a few clitics in Tommo So, including a plural marker =mbe and a definite marker =gɛ (an example showing both is given below). Clitics are always attached to the end of an entire noun phrase rather than the noun itself.

In general, clitics are always attached to the end of a stem, and never the beginning.

Reduplication

Reduplication is used for different purposes in Tommo So's morphology. The first is deadjectival nominalization, and the second is adjectival distribution.

Deadjectival nominalization

The process of nominalizing an adjective requires for the adjective stem to be reduplicated, either in part or in whole. At minimum, the first syllable is reduplicated. However, in the case of multisyllabic adjectives, up to the entire word can be reduplicated. A tone shift also occurs during this process. Regardless of how much of the original word is duplicated, the resultant noun has the same meaning.

Adjectival distribution

The reduplication of an adjective is used to distribute its meaning across a given number of objects.

néé-go=sɛ-m.
