Grammar Rule in 30 Seconds

Swahili verb extensions like '-i-' or '-e-' change their vowel to match the root's last vowel.

  • If the root ends in 'a', 'i', or 'u', use '-i-' (e.g., piga -> pigia).
  • If the root ends in 'e' or 'o', use '-e-' (e.g., soma -> somea).
  • The vowel 'a' is neutral and does not trigger the change.
Root (Vowel X) + Extension (Vowel X) + a

💡

Check the root

Always look at the last vowel of the root before adding any extension.
⚠️

Don't guess

If you aren't sure, check a dictionary for the root's final vowel.
🎯

Listen to the rhythm

Native speakers use harmony to keep the rhythm. If it sounds clunky, you probably have the wrong vowel.
💬

Use it to be polite

Adding the applicative suffix is a great way to sound more polite and native.

Smart Tips

Default to '-i-' for the extension.

pigea → pigia

Always use '-e-' for the extension.

somia → somea

Always use '-e-' for the extension.

letei → letea

Default to '-i-' for the extension.

fungulea → fungulia

تلفظ

pi-gi-a

Vowel length

Ensure the vowel in the extension is clear and distinct.

روش یادسپاری

تداعی تصویری

Imagine a party where vowels are guests. A, I, and U are wearing 'I' hats. E and O are wearing 'E' hats. They only dance with partners wearing the same hat.

Rhyme

If the root ends in A, I, or U, add an I to make it true. If it ends in E or O, use an E and watch it go.

Story

Juma wanted to cook (pika). He added an 'i' because 'a' is in the first group. Now he has 'pigia'. Then he wanted to read (soma). He saw the 'o' and knew he needed an 'e'. Now he has 'somea'.
