These seven words have the specific grammatical function of connecting elements of equal grammatical rank \u2014 words to words, phrases to phrases, independent clauses to independent clauses. Knowing how they work prevents some of the most common punctuation errors in academic writing.<\/p>\n<h1><span class=\"ez-toc-section\" id=\"What_coordinating_conjunctions_do\"><\/span>What coordinating conjunctions do<span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p>A coordinating conjunction joins two or more elements that have the same grammatical function.
