A mid-class consonant. It says ch at the start of a syllable and -t at the end. 8th in the alphabet, 5th of the 44 to learn here. You will meet it constantly.
01The sound it makes
4 of the 44 letters open a syllable with ch, so the sound on its own will never tell you which one you are looking at. 18 letters close one with -t, and จ is among them.
Mid class is the only class that takes all four tone marks, so จ can be written at any of the five tones. Take the live vowel away and it drops to low whether the vowel was short or long.
Live — carried on ◌า
Dead short — ◌ะ
Dead long — ◌าก
The 5 tones this ladder reaches
→Mid (สามัญ)A flat, neutral tone at a comfortable mid-pitch. No rise or fall.
↓→Low (เอก)Starts low and stays low. Slightly flat and subdued, like a quiet statement.
↘Falling (โท)Starts high then drops. Like English when expressing disappointment: "Oh..."
→↑High (ตรี)Starts at a high pitch and stays high, slightly rising. Energetic and bright.
↗Rising (จัตวา)Starts low then rises upward. Like English when asking a yes/no question.
The same letter is two sounds: จ is ch at the front of a syllable and -t at the back. Of the 4,271 words in this app it opens 126, sits inside 285 and closes 86.
Position here is orthographic — where the letter is written, not where it is said. The five leading vowels เ แ โ ใ ไ are skipped when deciding what comes first, so ไก่ counts as a word that starts with ก.
