Phrase pattern
Who → does what → what → number → classifier
The thing comes first, then the number, then the classifier
who+does what+what+number+classifier
Several rules work together in this pattern: who → does what → what; first the thing, then the number, then the classifier.
The guard eats three oranges
The friend writes three books
The student looks for three keys
Practice with this pattern changes the words each time. They come from the words you're learning.
Kai says
Thai digits have their own shapes: ๐ through ๙. The number practice helps you connect those shapes with values you already know.
