逾 (yú) is a formal/literary word that functions both as a verb meaning 'to exceed, to surpass' (often before numbers, e.g., 逾百人 'over a hundred people') and as an adverb meaning 'even more, increasingly' (similar to 更 but used in written Chinese). It appears in fixed expressions like 逾期 (overdue) and compound adverbs like 逾加 (even more). Learners should not use it in casual conversation—prefer 超过 or 更 in everyday speech.
