What is the difference between premier and premiere? Is it depend on masculine and feminine of the noun? How about deuxieme, is there a difference between masculine and feminine?

Bon samedi, Miche! Oui, tu as l'idée! = Yes, you have the idea. premier livre = first book (because le livre is masculine, the adjectival form is premier) but première maison = first house (because la maison is feminine and now the adjectival form is feminine too, or première.)

All adjectives depend TOTALLY upon the number (singular or plural) and gender (masculine or feminine) of the noun modified.

With deuxième there is only one singular form, as with troisième, quatrième, etc. The only one to worry about is "first" or premier/première.

Bonne question!

Mme

The difference between "premier" and "premiere" lies in their usage and meaning.

1. "Premier" (masculine) refers to the first or the best in rank, importance, or quality. It can be used as an adjective, noun, or adverb. For example:
- Adjective: "He is the premier player on the team."
- Noun: "The premier of the country will address the nation."
- Adverb: "They premier their movies at prestigious film festivals."

2. "Premiere" (feminine) is derived from the same root but is used specifically as a noun to refer to the first public performance or showing of an artistic or entertainment event, such as a play, film, or musical. For example:
- "The film had its premiere at the Cannes Film Festival."
- "The premiere of the new play received rave reviews."

Regarding the question of gender, neither "premier" nor "premiere" changes based on the gender of the noun in French. Both words have the same spelling and usage regardless of the gender of the noun they modify.

Similarly, for "deuxieme" (masculine) and "deuxieme" (feminine), both versions have the same spelling and meaning, regardless of the gender of the noun they are used with. The gender of the noun being modified does not affect the form of "deuxieme."
