突き当たる
つきあたる · tsukiataru · JLPT N2 · verb-godan
to run into
🚧 突き (tsuki, thrust/poke) + 当たる (ataru, hit/strike): a thrust that hits = to run into
突き当たる is built from 突く (to thrust) and 当たる (to hit), so it means to bump head-on into something. Sounds like 'tsuki' (moon) plus 'ataru' (a hit).
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.
