"Mets" is used when referring to the verb "to put" or "to place" in the imperative form for the pronoun "tu" (you singular). On the other hand, "nous" is used when referring to "we" and "vous" is used when referring to "you" in the plural form. "Nous" is used when talking about actions that involve yourself and others, while "vous" is used when addressing a group of people or showing respect to someone. **

"Mes parents" in French is "nous." The word "nous" means "we" or "us" in English, and it is used to refer to oneself and others. So, when saying "mes parents" in French, you would use "nous" to mean "we" or "us." **

The object pronouns me, te, nous, and vous are used to replace people or things that are the object of the verb in a sentence. "Me" is used for the first person singular (I), "te" is used for the second person singular (you), "nous" is used for the first person plural (we), and "vous" is used for the second person plural (you) or as a formal singular form. These object pronouns come before the verb in a sentence and help avoid repetition of nouns. **

In French, "on" is a more informal and general pronoun that can be used to mean "we" or "one" in English. It is often used in spoken language and is less specific than "nous." "Nous" is the more formal and specific pronoun for "we" in French and is used in more formal or written contexts. While "nous" specifically refers to a group of people, "on" can be used more broadly to refer to people in general. **

The letter "e" is added to the conjugation of "nous mangeons" in French to maintain the pronunciation of the verb stem "mange-". Without the "e", the pronunciation would be "nous mangons", which would alter the sound of the verb stem. The addition of the "e" helps to keep the verb's pronunciation consistent with the infinitive form "manger". **

In French, the phrase "et puis on mange" is used to say "and then we eat" because the pronoun "on" is commonly used to refer to "we" in a general or unspecified way. It is a more casual and informal way of expressing the action of eating without specifying the subject. On the other hand, "et puis nous mangeons" would be a more formal and specific way of saying "and then we eat," using the pronoun "nous" to explicitly refer to "we" as the subject of the action. **
