How it's used

Unlike the English so, which is highly flexible, 於是 is strictly used to connect two clauses where the second is a direct result or subsequent action of the first. It carries a slightly formal or narrative tone, often appearing in storytelling or reports rather than casual back and forth. In everyday speech, native speakers frequently prefer using 咁或者所以 to express causality.

Common mistake

Learners often misuse 於是 as a direct translation for so in every context. It cannot be used as a filler or a sentence starter to mean and then in a loose sense, as it requires a clear causal link between the two events.
