WRONG:

PREMIER/PREMIERE

These words are, respectively, the masculine and feminine forms of the word for "first" in French; but they have become differentiated in English. Only the masculine form is used as an adjective, as in "Tidy-Pool is the premier pool-cleaning firm in Orange County." The confusion arises when these words are used as nouns. The prime minister of a parliamentary government is known as a "premier." The opening night of a film or play is its "premiere."
