倚
yǐ · HSK 7
to lean on
🪑 亻person + 奇; same 奇 as 椅 the chair — a person leans on it
倚 pairs the person radical 亻 with the phonetic 奇 (qí), which also builds 椅 yǐ, the chair. Both share the lean-and-support sense: a person leaning on, or relying upon, something steady.
倚 — person radical 亻 + 奇 (qí, strange)
A semantic-phonetic compound. The person radical 亻 supplies the meaning—an action done by a person—while 奇 gives the sound (yǐ is a shifted reading of qí). The original sense was 'a person leaning on something,' which broadened to 'lean on, rely on, depend on.'
