Tone: Pitch Changes Meaning

Level 1

Twi is a tone language: each syllable is said high or low, and changing the pitch can change the meaning. Everyday spelling never marks tone.

How It Works

Two basic pitches. Twi syllables are high or low. A high syllable that follows a low one is said a little lower than the highs before it, so a long sentence often steps down like a staircase. A nasal that forms its own syllable, like the n in Yɛnkɔ, carries a pitch too.

Tone in words. Some words are spelled the same and told apart only by pitch:

  • papa: father, or good. Me papa wɔ fie (My father is at home); Ɔyɛ onipa papa (He is a good person).
  • dada: old, or already. The same letters, papa, also mean fan with a third melody.

Tone in grammar. Some verb forms are spelled the same and differ only in melody. The negative prefix is a low-pitched nasal, while the let or should prefix is a high-pitched one:

  • Yɛnkɔ! (Let us go!) and Yɛnkɔ (We do not go).
  • Ɔnkɔ can mean he does not go, or he should go.

See grammatical tone, N- negative prefix and optative N-.

Living with unwritten tone. Readers rely on context. Yɛnkɔ sukuu Memeneda is clearly about a habit (We do not go to school on Saturday), while Yɛnkɔ! said to friends at the door is an invitation. Learn words and phrases together with their melody, by listening and copying whole phrases. Dictionaries and linguistics books sometimes add accent marks to show tone, but normal Twi writing never does, so do not add them yourself.

Examples (5)

  1. Yɛnkɔ!

    Let's go!

    Word by Word: Let-us-go!

    With a high-pitched n, this is the let-us form.

  2. Yɛnkɔ sukuu Memeneda.

    We don't go to school on Saturday.

    Word by Word: We-not-go school Saturday.

    With a low-pitched n, the same prefix makes the verb negative.

  3. Me papa wɔ fie.

    My father is at home.

    Word by Word: My father is-at home.

    Here papa means father.

  4. Ɔyɛ onipa papa.

    He is a good person.

    Word by Word: He-is person good.

    Here papa means good. It is said with a different melody from papa (father).

  5. Mawie dada.

    I have finished already.

    Word by Word: I-have-finished already.

    Here dada means already. Said with a different melody, dada means old.

Common Mistakes

  • Dropping the n to avoid sounding negative.

    Yɛkɔ fie!
    Yɛnkɔ fie!

    Yɛkɔ fie means We go home, as a plain statement. Let us go needs the nasal prefix too; its high pitch, not the spelling, sets it apart from the negative.
