The Spanish conjunction 'si' is a word used to introduce conditional clauses or hypothetical situations. It is equivalent to the English word 'if'.
In Spanish, 'si' is commonly used in sentences that express a condition or possibility. It is often followed by the present subjunctive verb form, indicating uncertainty or doubt.
For example, 'Si llueve, no saldremos' translates to 'If it rains, we won't go out'. In this sentence, 'si' introduces the condition (llueve - it rains) and the result (no saldremos - we won't go out).
