Meaning and use

This pattern means “for the sake of,” “in the interest of,” or “for the purpose of.” The opening phrase names the aim or consideration; the clause after the comma states an action taken with that aim in view. The purpose often concerns coordination, protection, clarity, or a later process.

The outline lists this construction under purpose clauses at levels 7–9. That identifies the teaching scope here; it does not establish which version is currently administered at any test centre.

Formation and punctuation

为（了） purpose phrase 起见， main clause

Place 为 or 为了 before the purpose phrase, put 起见 at its end, then use a comma before the main clause. The optional 了 belongs in 为了; it does not replace 起见. The purpose phrase can be a verb phrase or a longer phrase naming an intended outcome. Keep the main clause complete.

Wèi quèbǎo shùjù de kěbǐxìng qǐjiàn, yánjiū tuánduì tǒngyī le cèliáng fāngfǎ.

为 + purpose + 起见， + main clause
为了 + purpose + 起见， + main clause
The parenthesized 了 in the outline marks the choice between 为 and 为了; the construction still ends the purpose phrase with 起见.

A useful contrast

A plain 为 / 为了 phrase can also introduce a purpose, but it does not use the specific frame ending in 起见. Compare the full pattern with an otherwise similar sentence that omits 起见. The latter may still be grammatical and convey a purpose; it is not an incorrect version of the target construction. Use 起见 when you want the more explicitly framed, considered tone.

为保护受访者的隐私，报告没有公布可识别个人身份的信息。

Wèi bǎohù shòufǎngzhě de yǐnsī, bàogào méiyǒu gōngbù kě shíbié gèrén shēnfèn de xìnxī.

A grammatical plain purpose sentence without 起见. It conveys the same protective aim in a shorter form; compare its wording with the more explicitly framed example using 起见.

Frequently asked questions

Where does 起见 go?

It closes the purpose phrase, immediately before the comma and the main clause.

Can I omit 了?

Yes. The outline gives 为（了）, so either 为 or 为了 can introduce the purpose; 起见 remains part of the construction.

Does the construction always sound formal?

It tends to sound deliberate and somewhat formal, though speakers may use it in ordinary conversation when they want to emphasize the consideration behind a decision.
