一括

いっかつ · ikkatsu · JLPT N1 · noun

all together

📦 一 (one) + 括 (tie up, bind) = tie everything into one bundle

括る (kukuru) means to tie up or bundle. 一括 combines 'one' with that idea, so it means handling many items as one bundle at once, like batch processing.

一 — single horizontal stroke
一 is one of the simplest pictographs in Chinese, depicting a single horizontal line to represent the number one. It has retained essentially the same form since oracle bone script over 3,000 years ago. By extension it also means 'first,' 'whole,' or 'same.'
