结
jié · HSK 4
tie
🪢 结 = 纟(silk thread) + 吉 (jí, lucky) — a lucky knot tied in silk
The 纟radical marks thread/cord words; 吉 hints at the sound jié and at the Chinese tradition of decorative 中国结 (Chinese knots) hung for good fortune. Meaning fans out from knot to tie, weave, and conclude.
结 — silk radical 糸 + lucky 吉 (phonetic)
结 is a semantic-phonetic compound. The silk radical 糸 on the left signals the meaning, since the original sense was tying threads or cords into knots. The right side 吉 (jí) provides the sound. From the literal 'knot' it extended to figurative senses like 'bind,' 'conclude,' or 'form (a bond).'
