U+788D "碍" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
碍
U+788D "碍" CJK Unified Ideograph-# is a Chinese character that primarily means "to hinder," "to obstruct," or "to be in the way," and is also used in compounds like "障碍" (obstacle) or "妨碍" (impede). It is composed of the stone radical 石 on the left, suggesting hardness or immovability, and the phonetic component 得 on the right, which contributes to its pronunciation (ài in Mandarin). This character appears in traditional and simplified Chinese texts, as well as in Japanese (where it is read as "sama" or "ge" in some contexts) and Korean, serving as a common logograph for expressing physical or figurative obstruction.
