積
積 ＝ 禾 ＋ 責
ㄐㄧ · jī
verb — to pile up, accumulate
字源 FORM — what the parts do
禾義grain on the stalk
{z,c,s}↔{j,q,x}IFTzé → jī — the same 責 turns jī again in 績
Grain (禾) stacked after the harvest — to pile up. 責 zé carries the sound, worn around to jī; 績 took the same turn. From the grain-stack, whatever gathers: 累積、積蓄 — and a surface reckoned up whole, 面積.
故事 STORY — a scene to remember it by
收割完，禾（禾）捆一層壓一層，垛子比屋簷還高。
Harvest done, the sheaves (禾) go down layer on layer — the stack rises past the eaves.
