The character in a word

A lone character is hard to remember: memory holds on to meaning, and a letter has none. The word it stands in provides that anchor.

The character in the “vowel marks around the letter” group

Shown on the carrier อ, as in a Thai classroom: by itself a vowel mark is not readable. Short and long pairs (ะ/า, ิ/ี, ึ/ื, ุ/ู) carry meaning as firmly as ship and sheep. They also decide whether the syllable is live. A short vowel with nothing after it makes the syllable dead, and that changes the tone.

How to remember this character

A single letter is the hardest thing to remember: memory has nothing to hold on to — a character has no meaning. A three-step loop works: see the character, try to recall the sound (for «sara uu» it is “long uu (below)”, as in the word “คุณ”), see the right answer.

And come back to it the next day, not in an hour: a check a day or two later beats a check the same day. Nobody holds the whole alphabet — 63 letters — at once.
