扎根
zhā gēn · HSK 7
to take root
🌱 扎根 = 扎 (stick in, plant) + 根 (root) = drive roots in, take root
扎 means to prick or plant firmly into something; 根 is a root. Together they describe roots digging into soil — and figuratively, a person or idea settling permanently into a place.
扎 — hand radical 扌 + 乚
扎 is a phono-semantic compound. The hand radical 扌 gives the meaning, since the original sense involves piercing, tying, or pulling with the hand, while 乚 hints at the sound. Over time it broadened to cover 'prick,' 'tie up,' and 'plunge into.'
根 — tree radical 木 + 艮 (phonetic)
根 is a semantic-phonetic compound. The left side 木 ('tree') gives the meaning, since the character originally referred to the roots of a tree. The right side 艮 supplies the sound. From 'tree root' it extended to mean 'root, base, foundation' in general.
