Unicode Version 17.0
吸
U+5438 "吸" CJK Unified Ideograph-# is a Chinese character that primarily means "to inhale" or "to suck," encompassing actions like breathing in air or drawing in liquid, as well as metaphorical uses such as absorbing attention or attracting interest. It is composed of the radical 口 (mouth) on the left, indicating its connection to oral actions, and the phonetic component 及 (jí) on the right, which provides a clue to its pronunciation. Historically, this character has been integral to words like 呼吸 (hūxī, meaning "to breathe") and 吸收 (xīshōu, meaning "to absorb"), and it appears frequently in modern usage from medical contexts to everyday language across Chinese, Japanese, and Korean writing systems.
