Meaning

Unihan defines 竹 as ‘bamboo; flute’. In compounds it sits on top in a contracted form, as in 筆 ‘writing brush; write; stroke’ (simplified 笔) and 算 ‘count, calculate, figure; plan’. Mandarin reads it zhú; Japanese, take.

Origin and history

Wieger read the character as two stems of bamboo, “the twigs of which are not raised up, but drooping”. He noted its “Contracted form”, and called it the radical “of characters mostly referring to the many kinds or articles of bamboo”.

The brush under bamboo

筆, the writing brush, is filed under bamboo, radical 118 with six strokes more, and keeps the bamboo on top in its simplified form 笔. Bamboo is one of three plant radicals with pages here, with tree and grass.
