How do you use mein in a sentence?

"Mein" is German for "my". Here are some examples of how to use it in a sentence:

1. With a noun:

* "Mein Auto ist rot." (My car is red.)

* "Das ist mein Hund." (That is my dog.)

2. With a pronoun:

* "Mein Bruder ist ein Arzt." (My brother is a doctor.)

* "Mein Freund ist hier." (My friend is here.)

3. With an adjective:

* "Mein neues Kleid ist wunderschön." (My new dress is beautiful.)

* "Mein lieber Freund!" (My dear friend!)

4. In a possessive phrase:

* "Das ist der Hut meines Vaters." (That is my father's hat.)

* "Das Buch meiner Freundin ist interessant." (My friend's book is interesting.)

Note: "Mein" is only used when the noun or pronoun is singular and refers to something that belongs to the speaker. For plural or third person possession, you would use "meine" (my, mine).
