The Low Class Consonant

Lesson 6

The biggest group of consonants is the low class. Any consonants that are not middle class and high class belong here.

You will spend some time to remember all of them, but take your time!

First, we will start with the tone rule of low class consonants. Here I put the tone rules for middle class and high class consonants for you so you can see the differences.

Tone rules for middle class consonant
  • Open syllable:
    – Syllables ending with n, ŋ (ng), m, w, or y sounds, or a long vowel is a middle tone
    – Syllables with ำ (-am), เ-า (-aw), ไ- (ay), or ใ- (ay) vowels is a middle tone
  • Closed syllable:
    – Syllables ending with k, t, or p sounds, or a short vowel is a low tone
  • Tone marks:
    – ่ = low / ้ = falling / ๊ = high / ๋ = rising
Tone rules for high class consonant
  • Open syllable:
    – Syllables ending with n, ŋ (ng), m, w, or y sounds, or a long vowel is a rising tone
    – Syllables with ำ (-am), เ-า (-aw), ไ- (ay), or ใ- (ay) vowels is a rising tone
  • Closed syllable:
    – Syllables ending with k, t, or p sounds, or a short vowel is a low tone
  • Tone marks:
    – ่ = low / ้ = falling
Tone rules for low class consonant
  • Open syllable:
    – Syllables ending with n, ŋ (ng), m, w, or y sounds, or a long vowel is a middle tone
    – Syllables with ำ (-am), เ-า (-aw), ไ- (ay), or ใ- (ay) vowels is a middle tone
  • Closed syllable:
    – Syllables ending with  k, t, or p with/or a short vowel have a high tone sound
    – Syllables ending with  k, t, or p with a long vowel have a falling tone sound
  • Tone marks:
    – ่ = falling / ้ = high

The tone of closed syllable with a short vowel is different from when it has a long vowel. And the tone marks become one step higher. This tone mark ่ becomes a falling tone and the this tone mark ้ becomes a high tone.

That’s it! This is all about the tone rules in reading and writing Thai. If you like to see this rule in a table format, click here.

Lesson 7

In this lesson, we will break the low class consonants into three small groups. Starting from the most commonly used to the least ones.

Take your time memorizing all of the following consonants. Once you know all the consonants and their rules, the rest will be easy.

First group

LETTERSOUNDNAMEMEANING OF THE NAMEAUDIO
nɔɔหนู (nǔu)a mouse
mɔɔม้า (máa)a horse
ŋɔɔงู (ŋuu)a snake
yɔɔยักษ์ (yák)a giant

ยุงเยอะยากยุ่งย้าย
เร็วรักรีบเริ่มรู้
เลลึกโลกลู่โล้น
วันแวะวาดว่ายแว้บ

Can you read all the above words correctly? If not yet, that’s not your fault. You need more time to work on it. But if you are ready, let’s move to the next group.

Second group

Are you ready for the last group of consonants? If yes, let’s rock it!

Last group

LETTERSOUNDNAMEMEANING OF THE NAMEAUDIO
nɔɔเณร (neen)a novice monk
yɔɔหญิง (yǐŋ)a woman
khɔɔระฆัง (rákhaŋ)a bell

thɔɔธง (thoŋ)a flag
lɔɔจุฬา (culaa)a star-shaped kite
hɔɔนกฮูก (nók hûuk)an owl

We will not have reading practice for this group because there are not many words that begin with these letters.

I’d recommend you learn their characters and sounds. You still need to know them all because you will see them as a part of a word.

To wrap up

Congratulations! You have learned all the Thai consonants with their tone rules. We’ve also covered all 18 single vowels so far. The rest will be easy once you feel confident with these 7 lessons.

Here is a list of what you have learned from these two lessons.

  • Learn a tone rule of low class consonant
  • See how the tone rules are different among all three classes of consonants
  • Complete the rest of the consonants

Are you ready for the rest? Let’s do it!
