Phrase pattern
Who → does what → to whom → แล้ว
แล้ว marks a finished action and goes at the very end of the sentence
who+does what+whom or what+แล้ว
Several rules work together in this pattern: who → does what → what; a marker sets the time: จะ before the verb, แล้ว at the end.
Mum has already forgotten a spoon
Dad has already called Grandma
The lecturer has already chosen prawns
Practice with this pattern changes the words each time. They come from the words you're learning.

The transcription uses bp and dt for sounds without an extra puff of air. The letters p and t mark their aspirated partners.
