覚え方のコツ Memory Tip
reckon は「計算する」「見積もる」、-er は「人・道具」なので、reckoner は文字どおり「計算する人・もの」です。現代の日常英語では calculator のほうが一般的ですが、a quick reckoner は「早見表」の意味でも使われます。古風な計算係を思い浮かべると覚えやすい語です。
Separate reckoner into reckon, meaning “calculate or estimate,” and -er, which can name either a person or a tool that performs an action. Imagine a clerk who quickly and accurately totals accounts before electronic calculators existed. That image matches phrases such as “a skilled reckoner” or “an accurate reckoner.” Calculator is now the usual everyday word for a calculating device and often for a person who calculates. Also learn quick reckoner as an established expression for a table or guide that lets users obtain figures rapidly.

reckoner の語源・成り立ち Etymology
reckon「計算する、見積もる」に、行為者や道具を表す接尾辞 -er が付いた語です。reckon は古英語 gerecenian「説明する、詳しく述べる」に由来し、数を順に挙げることから計算の意味を持ちました。
Reckoner consists of reckon and the agent or instrument suffix -er, so it can denote someone or something that performs calculations. Reckon descends from Old English gerecenian, which meant to explain, relate, or recount in detail. The idea of setting things out or enumerating them contributed to later senses involving counting, calculation, and estimation. Although reckoner remains understandable from its parts, calculator has replaced it in many ordinary modern contexts.
