Tooro or Rutooro (, Orutooro, ) is a Bantu language spoken mainly by the Tooro people (Abatooro) from the Tooro Kingdom in western Uganda. There are three main areas where Tooro as a language is mainly used: Kabarole District, Kyenjojo District and Kyegegwa District. Tooro is unusual among Bantu languages as it lacks lexical tone. It is most closely related to Runyoro.

Phonology

Vowels

Tooro has 5 short vowels and 5 corresponding long vowels. It also has 3 diphthongs.

Nasal vowels

Vowels followed by a nasal cluster tend to be nasalised, even to the point that the nasal consonant is barely heard (e.g. Abakonjo [aβakṍːⁿd͡ʒo] "Konjo people").

Vowel lengthening

Vowels can be lengthened in these contexts:

Vowel shortening

Word-final long vowels are shortened, except if they are in the penultimate syllable of a noun phrase. As a result, the inherently long final vowel in obuso "forehead" and the phonetically long final vowel in omutwe "head" are shortened in isolation but are lengthened after a monosyllabic qualifier (obuso bwe [oβusóː βwe] "his/her forehead"; omutwe gwe [omutwéː gwe] "his/her head").

Diphthongs

Tooro has 3 diphthongs, /ai/, /oi/ and /au/, the latter only being attested in 3 words, 2 being English loanwords (autu "vegetable cooking oil", etauni < Eng. "town", etaulo < Eng. "towel"). In some dialects, /ai/ is pronounced as [ei].

Vowel hiatus resolution

Tooro has different ways of resolving vowel hiatus in individual words or in between words:

Mid vowel harmony

Some suffixes that are added to verbs exhibit mid vowel harmony, where the vowel in the suffix (/i/ or /u/) is lowered to a mid vowel (/e/ or /o/ respectively) if the vowel in the ultimate syllable of the verb root is a mid vowel (e.g. okuc u mbira "to cook for someone"; okus e kera "to laugh for someone"). Mid vowel harmony does not apply if consonant mutation to the verb root also applies, instead only the consonant mutation in the verb root applies (e.g. ng e nzire (from the root √-gend-) "I went (and the effect remains)" instead of *ng e nzere).

Consonants

Consonant mutation

Certain suffixes, specifically the perfective -ir (not to be confused with the applicative -ir), the nominalizer -i, the short causative -i, and the long causative -is cause the consonant before it to be mutated. The first two suffixes mutate /ɾ, d͡ʒ/ or [d] to [z] and /t/ to [s] (e.g. barubasire "they have walked" < √-rubat- "to walk"; omubaizi "carpenter < √-baij- "to do carpentry"). However, perfective -ir mutates /d͡ʒ/ to [z] inconsistently (e.g. baizire "they have come" < √-ij- "to come"; bahiijire "they have panted" < √-hiij- "to pant"), and most of the time, it can be used with or without mutation (e.g. babaijire ~ babaizire "they have done carpentry" < √-baij-). The distinction between the perfective and applicative -ir is important as the applicative -ir cannot cause mutation (e.g. okurubatira "to walk for" < okurubata "to walk"). Additionally, only the unmutated perfective -ir can cause mutation, as the mutated form, -iz, cannot cause mutation (e.g. beereze "they have cleaned < √-eer "to clean" instead of *beezize). Causative -i also mutates /ɾ/ or [d] to [z] and [t] to [s] (no instance has been found of causative -i mutating /d͡ʒ/). Since the /zj/ and /sj/ clusters are not permitted in Tooro"s phonotactics, the /j/ is dropped (e.g. okukwasa "to make touch" < *okukwasya < okukwata "to touch"). Finally, causative -is only mutates /ɾ/ to [z] (e.g. okuhazisa "to cause to scratch" < okuhara "to scratch"). It cannot mutate /d͡ʒ/, [d] or /t/ (e.g. okutundisa "to cause to sell" < okutunda "to sell" instead of *okutunzisa).

Tone

Tooro has 2 main tones (high and low, low tone being the default), and 2 other tones (falling and rising) that appear in restricted circumstances. It is worth mentioning that vowels and nasal consonants can have a high tone (e.g. nnywa [ń̩ɲwa] "I drink").

High tone

Although Tooro lacks lexical tone, it has grammatical tone in the form of the high tone. In isolation, the high tone always falls on the penultimate syllable of a word, however, when a noun is modified by a following disyllabic adjective, the noun loses its high tone except if the noun functions as a predicate. -ona "all, whole" and -ombi "both" are exceptions to this, as they let the noun keep its high tone. Additionally, a noun followed by a monosyllabic adjective makes the high tone fall on the last syllable of the noun. An adjective with more than two syllables morphologically lets the noun keep its high tone. This means that ondi "the other (person, class 1)" & endi "the other (class 9)" are considered trisyllabic as they are derived from o-o-ndi/e-e-ndi and overlong vowels are not permissible. Thus, the only difference between [omuːntu óːndi] "another person" and [omúːntu óːndi] "the other person" is the high tone of the noun. Demonstratives also let the noun keep its high tone, regardless if the demonstrative has only 1 or 2 syllables.

Falling tone

A falling tone appears in two cases:

Rising tone

Rising tone is very rare, and only occurs in one case where a monosyllabic noun stem which has no noun prefix is used without an augment word-finally (e.g. enu ka [eːnǔ ka] "this is a house").

Phonotactics

The following syllable types are allowed in native Tooro words, where V stands for a vowel (short or long), C a consonant, N a nasal consonant, and G a glide. Note that since these rules only apply to native Tooro words, loanwords like Kristo "Christ" may break them.

Orthography

Tooro uses the same orthography as Nyoro. Vowel hiatus resolution between words is not indicated in the orthography, except for some short words like na "and", -a "of" or nka "approximately" (e.g. okusoma ekitabu [okusóm‿eːkitáβu] "to read a book"; ky'abantu [c‿aβáːntu] "of (class 7) the people"). Doubled vowels are not used in environments where vowel lengthening can be easily predicted (e.g. in a penultimate syllable before a nasal cluster). Tone is not represented in the orthography.

Grammar

Noun classes

Like most Bantu languages, Tooro has noun classes, shown in the table below (augment vowels in brackets). A noun is made augmentless (i.e. without an augment, equivalent to the base state in Luganda) in these circumstances: Compare the following examples:

Pronouns

Independent pronouns

Relative pronouns

Pronominal concords

Possessive pronouns and some other words like -a "of" and -ndi "another" are inflected depending on the noun class of the noun being qualified: These words support augments. For possessive pronouns, the augment conveys the meaning of "own" (e.g. omwana owange "my own child", instead of omwana wange "my child, any of my children"). For other words, it conveys definiteness (e.g. embuzi eya Bagonza "the house of Bagonza" instead of embuzi ya Bagonza "a house of Bagonza").

Demonstratives

Demonstratives in Tooro can optionally be placed before or after the noun (e.g. omuntu onu / onu omuntu "this person"). Classes 16 and 17 are used as adverbs (i.e. hanu means "here", kunu "this way", hali "there", kuli "that way")

Verbs

Tooro, like all Rutara languages, is a heavily agglutinative language, with verbs needing to agree with the tense, mood, subject and object in class and number. ti-ba-ka-ki-mu-h-es-er-a-yo-ga NEG-3PL.SM-REM.PST-CL7.DOM-3SG.IOM-give-CAUS-APL-FV-LOC-HAB They have never caused it (class 7) to be given to him/her over there. The morphological structure of a Tooro verb is:

Subject markers

Note the similarity to the subject concord prefixes. Only class 1 and 4 differ.

Object markers

Note the similarity to the subject markers, only class 1, 4 and 9 differ. The object markers are used for direct and indirect objects. The indirect object marker comes before the direct object marker: a-ka-ki-mu-h-a 3SG-REM.PST-CL7-3SG-give-FV he/she gave it (class 7) to him/her If the object marker is used with an object noun, the noun is made definite. Compare the following examples:

Verb derivation suffixes

Tooro has a lot of derivational affixes for verbs, most of them exhibiting mid vowel harmony. Reduplication is also used for some verbs (e.g. okutematema "to cut into small pieces using a machete").

Verb conjugations

Below are some verb conjugations in Tooro with examples that use the subject marker n- "I" and the verb root √-gend- "go". Perfective -ir is subject to mid vowel harmony and causes consonant mutation. Note that SM stands for "subject marker" and RT stands for "root".

Numbers

In Tooro, the numbers 1 to 5 are numerical adjectives that need to agree with the noun they qualify, whereas the numbers 6 to 10 are numerical nouns that do not agree with the qualified noun. For abstract counting, the class 10 inflection of the numerical adjective is used. 20 to 50, 200 to 500 and 2000 to 5000 are expressed using the plural of 10, 100 and 1000 respectively with the cardinal numbers for 2 to 5. 60 to 100, 600 to 1000 and 6000 to 10,000 are numerical nouns derived from the same roots as 6 to 10.

Time-telling

In Tooro, time is counted in a 12-hour time convention from sunrise to sunset, with 7:00 am being the first hour of the day and 6:00 pm being the twelfth. Same goes for 7:00pm and 6:00 am respectively. To tell time, use saaha ("hour") + the corresponding number of the hour (equivalent of subtracting 6 from the A.M./P.M. system). The class 16 locative class is used for time (e.g. tukahika hasaaha ikumi "we arrived at four o'clock").

Greetings (Endamukya)

Greetings in Tooro differ depending on number (singular or plural):
