两岸
liǎngàn · HSK 5
both sides of a river
🏞️ 两 = two + 岸 = shore/bank; together: the two banks (of a river/strait)
两 means 'two' and 岸 means 'shore' or 'riverbank'. So 两岸 literally reads as 'two shores' — the two sides of a river. Politically it's shorthand for the two sides of the Taiwan Strait: Mainland China and Taiwan.
两 — two halves under 一, mirrored 入 components inside 冂
两 originally depicted a balance scale or a pair of matched objects, symbolizing duality and equality. The two inner components represent the two equal sides being weighed or paired. Over time it came to mean 'two' (especially for paired things) and also a traditional unit of weight (tael).
岸 — mountain 山 on top + cliff 厂 + 干 (phonetic)
岸 is a semantic-phonetic compound. The top combines 山 (mountain) and 厂 (cliff/slope), suggesting a steep landform by the water; 干 underneath supplies the sound. Together it depicts a high bank or shore where land meets water.
