Thai Consonants

Notes:

1. ฃ, ฅ, and ฦ are considered obsolete.
2. ฤ and ฦ are usually not classified as constants but as special vowels which include a consonant sound. However, they behave like consonants with respect to tones and dictionary ordering when they provide the first consonant sound in a syllable.
3. Sources disagree on whether ซ and ฌ may end a syllable.
