to burn
🍞🔥 焦 has the fire radical 灬 underneath, so kogeru means scorch by fire
Kogeru is what toast does when left too long. Its sound matches koge, the scorched rice crust stuck to the bottom of a pot.
焦 — bird 隹 over fire 灬
焦 is an associative compound showing a short-tailed bird (隹) above fire (灬), depicting roasting a bird until scorched. The original sense was 'burnt' or 'charred,' which extended to 'scorched, dried out,' and metaphorically to 'anxious, worried' (as in 焦急).
