Common questions about Igbo
How does Igbo aspect work?
Igbo marks aspect at both ends of the verb. The prefix na- gives imperfective: ọ na-eri ('she is eating', 'she eats habitually'). The suffix -rV (where V copies the verb root vowel) gives perfective: ọ riri ('she ate', 'she has eaten'). The bare stem is inherently completive: ọ ri (in commands, 'eat!'). These three forms cover ongoing, completed-with-relevance, and bounded aspect.
What is Igbo vowel harmony?
Igbo divides its vowels into two harmonic sets: [+ATR] (i, e, o, u) and [-ATR] (ị, a, ọ, ụ). Within most words, vowels stick to one set — they don't usually mix. Suffixes typically have two surface forms, one for each set, and the stem's vowel determines which form attaches. ATR ('advanced tongue root') refers to the physical position of the tongue when producing the vowels.
Is Igbo tonal?
Yes — Igbo has two underlying tones: high and low. Tone distinguishes words that would otherwise be identical: ákwá ('cry', high-high), àkwà ('cloth', low-low), ákwà ('bed', high-low), àkwá ('egg', low-high). The four meanings come from four tone patterns on the same syllables. Tone also has grammatical functions, distinguishing subject from object in some constructions.
Does Igbo have grammatical gender?
No. Igbo nouns and pronouns don't mark gender. The 3rd-person pronoun ọ (dependent) and ya (independent) means 'he', 'she', or 'it' depending on context. Adjectives don't change shape. Igbo is one of many West African languages without grammatical gender. The few words that distinguish gender are kinship terms or borrowings.
Why does Igbo use plural 'you' for one person?
The plural pronoun unu addresses a single respected individual — an elder, a chief, a title-holder. Using the singular gị to such a person is rude. Igbo culture has elaborate respect protocols, and the plural-as-honorific is a grammatical reflection of this. The same pattern appears in Yoruba, Hausa, and many other West African and global cultures (German Sie, French vous).
