Phrase pattern
Who → does what → อะไร
อะไร, what, goes where the answer would be: at the end, not at the start
who+does what+อะไร
Several rules work together in this pattern: who → does what → what; a question word goes where the answer would be.
What does Grandpa drink?
What does the guard forget?
What does the teacher read?
Practice with this pattern changes the words each time. They come from the words you're learning.

The g in the app's transcription is an unaspirated k sound, not the voiced g in English go. The recording is your guide to the difference.
