Phrase pattern
When → who → does what → to whom
Say tomorrow and you don't need a marker: the time word already sets the time
when+who+does what+whom or what
Several rules work together in this pattern: who → does what → what; a time word goes at the start or the end of the sentence.
Mum will put on shoes tomorrow
The man is waiting for the child now
The woman remembers Grandpa now
Practice with this pattern changes the words each time. They come from the words you're learning.
Kai says
High, middle and low are consonant classes, not instructions to raise or lower your voice. The class works with the rest of the syllable to determine its tone.
