Etymology & Meaning · 字义溯源
### Soundyì — yì (4th tone). Often a bound morpheme — needs a partner word ### Original meaningYì (4th tone). The Shuowen Jiezi defines it as 「安也。从人𢡃聲」 — 'peace, settledness': a person radical with 𢡃 (the old graphic form later written 意) as phonetic. Everything a buyer sees in the character today belongs to a second job. Duan Yucai lays out the sequence exactly: 「此億字之本義也。今則本義廢矣。或假爲萬億字,諸經所用皆是也……《左傳》曰不能供億,曰心億則樂,曰我盍姑億吾鬼神,而寧吾族姓,杜注皆曰:安也」 — 'this is the original meaning, but the original meaning is now abandoned; it was borrowed for the word hundred-million, and every classic uses it that way'. The classics Duan cites bear him out: 《詩·魏風·伐檀》「三百億兮」 and 《易·震》「億喪貝」, where Zheng Xuan notes 「十萬曰億」 (the count was not fixed — the 《禮記》疏 records both a decimal and a myriad-scale reckoning). The Kangxi adds the sense of supplying enough: 「又供億,謂供其匱乏,使之安也」. The honest picture: a word for being at peace that was reassigned to arithmetic, and never given back. ### The structure (形聲 · 从人,𢡃聲 — the settled person; the phonetic 𢡃 (later written 意) also carries 'fullness')①人rénpersonpeace located in a person, not in circumstances②𢡃yìfull / satisfiedthe phonetic, later simplified in script to 意③億yìpeace (Shuowen)the abandoned original meaning④意yìthought / intentionthe modern lookalike; 億 borrows back from it for 'to conjecture' (億則屢中) ### In use todayItemReading / meaningNoteReadingyì (4th tone)single syllableCore sensea hundred million; countlessShuowen root was 'peace'Grammarbound morpheme / numeral億萬 · 億兆 · 億載 — multitudes and long spansTattoo fitcaution — reads as a figuresay plainly that the peace sense is obsolete ### Closest words in English — and what each misses - Peace — 安/寧 hold settled peace; 億 held it once and lost it — no modern reader recovers it - Infinity — 億 is a definite number, historically ten thousand × ten thousand — large, not endless - Wealth — 富/財 hold riches; 億 counts things, including people (億兆 = the masses) - Eternity — 億載 means 'myriad years', which is long but still counted; 永 is the word for unendingAn honest note on grammar. Bound morpheme: 億萬 'myriads', 億兆 'the innumerable multitude', 億載 'ten thousand years'. Also a surname; also borrowed for 臆 ('to conjecture') in 「億則屢中」 《論語·先進》.Where a Western reader can stand: 億 (yì) is 'a hundred million' — the word for enormous number and multitudes. Its Shuowen definition is actually 'peace', and the great Qing philologist Duan Yucai notes flatly that this original meaning was abandoned once the character was borrowed for counting: every classic uses it as a number. So the honest piece of writing here is
Cultural Story
The "Hymns" sing of a good year, "万亿及秭" — ten thousands and a hundred millions and beyond — 亿 among the numbers of abundance piled in the granary. The word 億 was the ancient measure of the uncounted plenty, the grain and the years alike. To say 億 was to confess that the store passed counting.

Its Shuowen definition is actually 'peace', and Duan Yucai notes flatly that this original meaning was abandoned once the character was borrowed for counting: every classic uses it as a number. So the honest swap is the story: a word for a settled heart that got hired out to arithmetic, from the Zuo Zhuan's 『when the heart is settled, there is joy』 to a modern figure. Wear it for plenty, and say so honestly.

Read the story behind the character
The budget runs to 億元 and the fund holds 億萬; a 十億 deal closes before lunch. The word still means the huge count — a hundred million, a vast sum — the figure that signals scale beyond the everyday, in the annual report, the infrastructure bid, and the headline where the nation tallies what it has and what it owes.
