'如果' (rú guǒ) is a conjunction meaning 'if', used to introduce a hypothetical or conditional clause. It is composed of two characters: '如' (rú), meaning 'as' or 'like', and '果' (guǒ), meaning 'result' or 'consequence'. Together, they literally suggest 'as [a] result' — emphasizing the causal link between a condition and its outcome. Unlike single-character '若' or literary '倘若', '如果' is standard in modern spoken and written Mandarin, neutral in register, and widely used in everyday conversation, instructions, and formal writing.

It typically appears at the beginning of a subordinate clause, followed by a main clause expressing the consequence. The structure is usually '如果 + [condition], (then) + [result]'. While the 'then' part is often omitted in informal speech, the conditional relationship remains clear. '如果' can express real possibilities ('If it rains, we’ll stay home') or unreal/hypothetical situations ('If I had time, I’d study Chinese every day'), depending on verb aspect and context.
