Step 5: live and dead syllables
What you will be able to do
Look at any syllable you can read and say whether it is live or dead, because that decides which tones it can carry.
Thai syllables come in two kinds, and the difference decides everything in the next step. A LIVE syllable can be hummed. It ends in a long vowel, or in a sonorant consonant: n, m, ng, y or w. กา (gaa), ดี (dii) and จาน (jaan) are live; say them and you can hold the final sound as long as you like. A DEAD syllable stops. It ends in a stop consonant, p, t or k, or in a short vowel. จาก (jàak) ends in a k you cannot hold; ปะ (bpà) is cut short by the vowel itself. That is the entire distinction. Read any word you know and ask: can I hum the ending? Then it is live. Does it stop? Then it is dead. Why it matters: an unmarked live syllable and an unmarked dead syllable take DIFFERENT tones, and some tones are simply impossible on a dead syllable. The next step uses this constantly, which is why it gets a step of its own now, while the words are still simple.

Common mistake
The letter that closes a syllable often changes its sound: บ at the end is pronounced p, ด becomes t, ก stays k. ดิบ (raw) ends in a p sound, not a b. Read finals with the ear, not the letter name.
