Tips

register

Two other readings split off into compound-only territory. Capitalized 哈 is the proper-noun reading used as an abbreviation in country and city names - 哈萨克斯坦 (Kazakhstan) and 哈尔滨 (Harbin); same syllable, just flagged as a name. Third-tone hǎ appears almost exclusively in 哈巴狗 (pug / pekingese; figuratively a sycophant) and in dialect speech meaning to scold. For everything else - laughter, transliterations like Harvard / Harry / Manhattan / Häagen-Dazs, husky dogs, and 哈欠 (yawn) - use first-tone hā.

memory

Mouth radical 口 on the left, 合 on the right: an open mouth letting out a breath - exactly what you do when you laugh, yawn, or fog up a window with 哈.

Components

radical

口 kǒu

mouth

Mouth radical on the left - also 哈's indexing radical (Kangxi #30). Direct semantic match for an interjection: 哈 is purely a mouth-noise, the sound of laughter or surprise. Same radical in a huge family of speech and onomatopoeia chars: 吃, 喝, 叫, 吧, 啊.

phonetic

合 hé

join; close together

Right side 合 supplies the sound: hé shifted to hā via vowel change. Same phonetic in 给, 答, 拾, 塔 - the 合 cluster spans h-/g-/d-/t- readings due to deep Old Chinese variation. Pure phonetic role; the joining meaning of 合 is irrelevant to the laugh-noise sense here.
