laugh heartily, laugh aloud
噱 centers on loud, hearty laughter: laughing aloud or laughing heartily, the kind of open-mouthed sound that fills a room.
噱 combines 口 (mouth) with 豦, which likely contributes the sound and may relate to a wild boar or a large animal, suggesting a loud, boisterous noise from the mouth. The exact historical development is uncertain.
The left side is a mouth 口, and the right side 豦 looks like a wild boar with its snout and bristles. Imagine a boar-like laugh bursting from a wide-open mouth: loud, hearty, and impossible to ignore.
For キャク, picture a comedian cracking a joke so funny that the audience lets out a sharp, barking laugh: kyak! The sudden kyak sound cues キャク while the mouth 口 laughs heartily.
