🍎💪 结 = tie/knot + 实 = fruit/solid → knotted-up fruit = sturdy
结 means to tie or form a knot; 实 means fruit or solid/real. Together: a plant bearing knotted fruit, extended to anything solid and tough. Note 实 is neutral tone here (jiē shi), not jiē shí.
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).'
