English

If, because, when: ถ้า, เพราะ, เมื่อ

Two short phrases are stitched together by a conjunction — a word between them. ถ้า — if: thaa fon tok yuu ban — if it rains, (I stay) home. เพราะ — because: yuu ban phro fon tok — home, because it is raining. For example: “ถ้า ฝน ตก อยู่ บ้าน” — If it rains — home. A rule from the Thai course: worked out on examples, not memorized as a wording.

How it works

Two short phrases are stitched together by a conjunction — a word between them. ถ้า (тхаа) — if: thaa fon tok yuu ban — if it rains, (I stay) home. เพราะ (пхро) — because: yuu ban phro fon tok — home, because it is raining.

เมื่อ (мыа) — when: muea thetsakan ma — when the festival comes. And there is เลย (лёй) — so, therefore; it stands after the cause: fon tok loey yuu ban — it is raining, so (I am) home.

The verb inside the second half changes in none of these cases: Thai does not sequence its tenses. Thai writing needs no comma here: the conjunction holds the two thoughts together. The word order stays as in two separate phrases.

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
