当～
とう～ · tou～ · JLPT N1 · noun
gram
🏨✈️ 当 = facing us: the one right in front of us, so it means our or this
当 originally meant to face or match, so it marks the one directly before us. Examples: 当ホテル (our hotel), 当機 (this plane), 当社 (our company).
当 — small ⺌ + crown 冖 + hand 彐 (simplified from 當: 尚 + 田)
Originally written 當, combining 田 'field' with 尚 as a phonetic. The early sense was 'to match' or 'face' a field of equal value, extended to 'correspond to', 'ought to', and 'serve as'. The simplified form 当 streamlines the upper 尚 component.
