Is Supercalifragilisticexpialidocious an actual word?

The history of Supercalifragilisticexpialidocious is an interesting one. The word is at the heart of the Sherman brothers’ song for Disney’s Mary Poppins film in 1964

However, the Oxford English Dictionary records a very similar word in the column "A-muse-ings" by Helen Herman in the Syracuse University Daily Orange. This word was supercaliflawjalisticexpialadoshus.

In 1965, there was an unsuccessful lawsuit by songwriters Gloria Parker and Barney Young against Disney's music publishing subsidiary Wonderland Music. They claimed it was copyright infringement of the 1949 song Supercalafajalistickespeealadojus.

Since variants of the word were known before 1949, Disney won the case, and today can we call say supercalifragilisticexpialodicious as much as we all desire!
