Conjugating 'Um-' for Present Actions
Grammar Rule in 30 Seconds
The 'um-' infix turns a root word into an active verb by inserting 'um' after the first consonant.
- If the root starts with a consonant, insert 'um' after it: 'kain' becomes 'kumain'.
- If the root starts with a vowel, add 'um' to the front: 'alis' becomes 'umalis'.
- These verbs focus on the person doing the action, not the object being acted upon.
