以便 (so that / in order to)

• Pinyin: yǐbiàn
• Formation: Action / Preparation + 以便 + Desired Outcome
• Hanzi breakdown: 以 = 人 (person) variant + 丶; 便 = 亻(person) + 更 (change)

Meaning

The conjunction 以便 (yǐbiàn) means 'so that' or 'in order to' and connects an action with its intended outcome. It introduces a purpose clause, indicating that the first action is performed to facilitate or enable the second.

As a formal purpose connector, 以便 is more literary and precise than colloquial alternatives like 好 or 这样. It is widely used in official documents, business communication, academic writing, and formal instructions. Unlike 为了 which introduces purpose at the beginning, 以便 typically appears between two clauses — the preparatory action comes first, followed by 以便 and the desired result. It is interchangeable with 以利于 in some formal contexts. Compared to 好 (which serves a similar purpose colloquially), 以便 sounds significantly more polished and professional. Learners should note that both clauses usually share the same subject, though different subjects are possible in formal writing.

Origin & History

The word 以便 combines 以 (in order to, by means of) with 便 (convenience, ease). This compound emerged in formal written Chinese to express facilitative purpose, and it remains a staple of official and professional language today.
