Treguna Mekoides Trecorum Satis Dee is a made-up language in the 1971-released Disney film Bedknobs and Broomsticks. Perhaps its means "Rough goat three-member team sufficiently dizzy" since the spell brings an inanimate object to life and since the words respectively resemble Greek trakunnien for "to become rough," Greek Mhkados for "bleating like a goat," Latin trigarum for "team of three," Latin satis for "sufficient" and Latin-like dee for "to be dizzy."

The words mean nothing. Disney isn't J. K. Rowling. They just came up with some impressive-sounding nonsense words which sound vaguely like Latin.
The one she casts repeatedly is a transfiguration human-to-animal spell. We never hear the exact name. It goes, "Filigree, Apogee, Pedigree, Perigee. The most notorious spell from the entire movie is the Substitutiary Locomotion spell and is engraved on the 'Star of Asteroth'. It goes, "Traguna, Mekoides, Trecorum, Satis dee". The "Famous Travelling Spell" that Ms. Price casts over Paul's Bedknob goes, "Hellbore, Henbane, Aconite, Glow worm fire, Fire fly light." She also uses an "All purpose cut-off spell" but we never see it preformed or hear the words in the movie.
