Logba has a nine
vowel system with
ATR vowel harmony. Vowel harmony in Logba is root-controlled, which means that the vowels of its nominal prefixes harmonize with the vowels of the root. Vowels are nasalized when they occur in the immediate environment of a nasal consonant. Logba is a
tonal language with two level tones: High and Low. These tones can be combined on one syllable, yielding a Rising or Falling contour tone. All
syllables are open in Logba. Every syllable bears a tone. The basic syllable structure can be rendered as (C1)(C2)V+T, where C = consonant, V = vowel or syllabic nasal, and T = tone. Dorvlo (2004) distinguishes three types of syllables: •
Nucleus only, consisting of a vowel or a
syllabic nasal. This type is found only in pronouns and nominal prefixes. Examples:
ɛ́-mɔ́ 'they laughed';
ɔ́-zɔ́ 'he/she went';
n-dà 'liquor'. •
Onset and nucleus. This is the most common syllabe type in Logba; most words are of this form. In multisyllabic words, it can occur in all positions. Examples:
bà ‘come’;
gbà ‘sweep’;
bìsí ‘cola nut’ • Complex onset and nucleus. Only /r/ and /l/ occur as the second consonant of the complex onset. This syllable type can also form a word by itself. In multisyllabic words, in can occur in all positions. Examples:
à-klɔ́ ‘goat’;
trò ‘refuse’;
ìvàflí ‘(thing) white’.
Consonants The consonants of Logba are as follows: s, z, ts, and dz are palatalized to ʃ, ʒ, tʃ, and dʒ respectively, when they occur before i. In the Tota dialect, t and d are pronounced as ts and dz before u.
Tone Logba is a
tonal language with two tones, high and low. There are a few words which have rising tone, all of which are either loanwords such as zenklǎ (pot stand), a loan from
Ewe, or are ideophonic, such as tǒ (to fell
palm trees), which imitates the sound of a palm tree falling. Monosyllabic verbs which have a low tone in their uninflected form gain high tone when inflected. ==Notes and references==
