Conjunction Junction was a popular educational animated musical segment from the ABC television series Schoolhouse Rock!, which aired from 1973 to 1985. The segment was created by David McCall and was first aired on January 13, 1973. The purpose of the segment was to teach children about grammar, specifically conjunctions, which are words that connect two or more words, phrases, or clauses.
The segment featured a catchy song, written by Bob Dorough, that explained the function of conjunctions and gave examples of how they are used. The song was sung by Jack Sheldon, who also provided the voice of the animated train conductor character that guided viewers through the lesson. The segment was animated by Phil Kimmelman and Associates.
