Paired conjunctions as Conveyors of alternatives

A conjunction is a word or expression that acts as a transition between clauses and phrases in a complex sentence. For example: "不但……而且……" búdàn...érqiě... (not only … but also …), "如果……就……" rúguǒ...jiù... (if… then…), and "总而言之" zǒng'éryánzhī (all in all), where the first clause or phrase is connected to the following clause or phrase by a conjunction.

The paired conjunctions such as "不是……就是……" búshì...jiùshì..., "或者……或者……" huòzhě...huòzhě, "要么……要么……" yàome...yàome..., "是……还是……" shì...háishi indicate alternatives in a complex sentence.
