即便 is a conjunction meaning 'even if' or 'even though', used to introduce a concession — that is, a condition or fact that might seem to prevent something from happening, yet the main clause still holds true. The character 即 means 'immediately' or 'just', suggesting immediacy or inevitability, while 便 means 'then' or 'thus', indicating a natural consequence. Together, they form a fixed compound expressing strong contrast and unwavering conditionality.

This word is formal and literary, commonly found in written Chinese, speeches, and thoughtful spoken discourse — less frequent in casual conversation, where even if (even though) is often replaced by simpler structures like 虽然…但是 or 就算. It typically precedes a noun phrase, verb phrase, or clause and must be followed by a main clause expressing the resulting action or state despite the concession.
