, often appears between the conjuncts, usually at least between the penultimate and ultimate conjunct of the ''coordinate structure''. The words ''and'' and ''or'' are by far the most frequently occurring coordinators in English. Other coordinators occur less often and have unique properties, e.g. ''but'', ''as well as'', ''then'', etc. The coordinator usually serves to link the conjuncts and indicate the presence of a coordinate structure. Depending on the number of coordinators used, coordinate structures can be classified as
syndetic,
asyndetic, or
polysyndetic.
Different types of coordinators are also categorised differently. The table below shows the categories for the coordinators in English:

phrasal category can be coordinated. The examples throughout this article employ the convention whereby the conjuncts of coordinate structures are marked using square brackets and bold script. In the following examples, the coordinate structure includes all the material that follows the left-most square bracket and precedes the right-most square bracket. The coordinator appears in normal script between the conjuncts.
