栽
zāi · HSK 7
to grow
🌱 木 wood/tree + 𢦏 (the zāi sound shared with 裁 and 載) = to plant a tree
The 木 component marks the meaning (trees, planting), while 𢦏 supplies the zāi reading. By extension 栽 stretches from planting to inserting or forcing something onto someone.
栽 — plant 𢦏 (phonetic) + tree 木
A semantic-phonetic compound: 木 (tree/plant) gives the meaning, while 𢦏 (zāi) supplies the sound. Originally referred to planting saplings or seedlings in soil, and by extension came to mean 'to plant, cultivate, or grow' more generally, as in 栽培 (to cultivate).
