The conjunction 'if' introduces conditional sentences, which can be real ('if it rains, we'll stay inside') or hypothetical ('if I were rich, I would travel'). 'If' also means 'whether' in reported questions ('I asked if he was coming'). Understanding conditional structures is essential for expressing possibilities and hypotheticals.

「if」引导条件句，可以是真实条件（「if it rains, we'll stay inside」）或假设条件（「if I were rich, I would travel」）。「if」在间接疑问句中也表示「是否」（「I asked if he was coming」）。理解条件句结构对于表达可能性和假设非常重要。

La conjunción «if» introduce oraciones condicionales, que pueden ser reales («if it rains, we'll stay inside») o hipotéticas («if I were rich, I would travel»). «If» también significa «si» en preguntas indirectas («I asked if he was coming»). Comprender las estructuras condicionales es esencial para expresar posibilidades e hipótesis.

「if」は条件文を導入し、現実的（「if it rains, we'll stay inside」）または仮定的（「if I were rich, I would travel」）のいずれかです。「if」は間接疑問文で「〜かどうか」も意味します（「I asked if he was coming」）。条件文の構造を理解することは、可能性や仮定を表現するために不可欠です。

접속사 'if'는 조건문을 이끌며, 현실적 조건('비가 오면 안에 있을 거야')이나 가정적 조건('부자라면 여행할 텐데')을 나타냅니다. 또한 간접 의문문에서 '~인지 아닌지'의 의미로도 쓰입니다('그가 오는지 물어봤다'). 조건문 구조를 이해하는 것은 가능성과 가정을 표현하는 데 필수적입니다.
