Tones in Ígálâ
Seven types of tones, among which five are lexical, are recognized in the language as illustrated in Table 1.1 (Èjèbá 49). Note that a “downstepped high” refers to the lowering of a syllable that is usually high-toned.
Table 1.1 Tones of Ígálâ
Tone | Example | Meaning | Comment |
---|---|---|---|
Extra high (EH) | (w)ɔ̋làdʒa̋ | Greeting for someone returning from market | Grammatical: “on subject clitics to mark sentential negation” (Èjèbá 49) |
High (H) | ɔ́dʒɔ́ | day | Lexical |
Downstepped high (HS) | ɔ́gbá ꜜúgúnú | in front of vulture | Grammatical, at high tone juncture of word boundaries. |
Mid (M) | ɔ̀tákídā | book | Lexical |
Low (L) | ɔ̀bàlà | cat | Lexical |
Rising (LH) | ǒkâ | one | Lexical, contour |

Beyond hiatusː words with different surface tones
Tonal changes of words involving contour
The falling contour in a word can be lowered when the syllable on its left has a lower tone due to hiatus.
ɛ́hʲâ -> ɛ̄hʲa᷆ in sentence. In (7), the tone of ɛ is M according to hiatus of M and H. As a result of the lower tone, the contour on the second syllable of ɛhʲa changes from a HL to ML.

Perfective Marker
Sentential tone and intonation
Downdrift
Downdrift is the cumulative lowering of pitch towards the end of the sentence. Sentences in Igala exhibit such a tonal profile in general.
Figure 5.1 Display of pitch contour with Praat
In the sentence shown in Figure 5.1, we see three intonation phrases with pause in between. In each section there is at least one syllable with a H tone. Across the three sections, the pitch value of the H tone decreases in the course of the sentence. The values are 304 Hz, 224 Hz and 179 Hz respectively.
Raise of first word before the first H
The first word of a sentence is usually raised in its pitch, but this applies to syllables up to and including the first H only.
