ใช้ เวลา เท่า ไหร่

In short

Why it looks that way

Literally "use time how much": chai is to use, and welaa is time. Thai keeps one question about the time it takes

A word with a story stays in memory longer than one learned as a “spelling — translation” pair: memory holds on to meaning, not to a string.

In a live sentence

A single word almost never appears alone in conversation. A sentence shows where it fits and what stands next to it.

  тхам ахан чай вэлаа тао рай

  How long does the cooking take?

How not to forget this word

Reading a word and remembering it are different jobs. A day later, little survives of a single reading — and that is not bad memory, that is how memory works.
