Explanation

After tone changes happen in Yoruba, “omo-ki-omo” becomes “omokomo.” The vowels and tones shift to create a smoother compound word.

Vowel elision removes some vowels when words join. This makes speech flow better. The “ki” disappears and tones adjust to fit the new pattern.

Sound changes make language easier to speak. Yoruba has rules for how words combine and change.
