赴く
おもむく · omomuku · JLPT N1 · verb-godan
to go
Contains the 走 (run) radical: to head off purposefully toward a place
The 走 radical means run or walk quickly, so 赴 means setting off with purpose toward a destination. Its reading, omomuku, is a separate sound to learn.
赴 — 走 'walk/run' + phonetic 卜
A semantic-phonetic compound: 走 (run, hurry) gives the meaning of going somewhere quickly, while 卜 supplies the sound. Originally meant to rush toward or hasten to a place, and still carries that sense of going to attend something, as in 赴会 'attend a meeting'.
