Clause connectors, also known as conjunctions, are words used to join two clauses together. The most common clause connector is 'AND, ' which is a four-letter word. Other clause connectors include 'BUT, ' 'or, ' 'SO, ' AND 'YET.' These words help to create complex sentences by connecting two independent clauses. They can also be used to connect two dependent clauses. Clause connectors are an important part of English grammar AND are used to make sentences more interesting AND easier to understand.
