仍旧 is an adverb meaning 'still' or 'yet', used to indicate that a situation, condition, or state continues unchanged from before. It combines the characters 仍 (réng), meaning 'still' or 'yet', and 旧 (jiù), meaning 'old' or 'former'; together they emphasize continuity — literally 'still the former'. It often appears in formal or written Chinese, but is also common in spoken language when expressing persistence despite expectation of change.

This word typically modifies verbs or adjectives and usually comes before the predicate. It carries a slightly literary or neutral-to-formal register, making it more common in essays, news reports, or careful speech than in casual texting or slang. Unlike the colloquial 还 (hái), 仍旧 subtly suggests endurance or resistance to change — for example, continuing a habit, maintaining a belief, or remaining in the same place or condition over time.
