Composition

遅い is built from 遅 meaning late or delay, plus the i-adjective ending い, turning the root into a descriptive adjective that conveys lateness or slowness.

Etymology

oso-i is the kun'yomi form associated with 遅; the modern 遅い results from attaching the い adjective ending to the kanji's root, reflecting a phonetic evolution from classical Japanese.

Origin

Old Japanese usage appears in classical literature; the concept of lateness or slowness existed across periods, and 遅い consolidated in the modern language.
