In German
mein
Meaning: my
Example sentences
DasistmeinBuch.
That is my book.
MeineSchwesterwohntinBerlin.
My sister lives in Berlin.
Grammar note
“Mein” takes the same endings as the indefinite article “ein”: “mein Buch” (neuter), “meine Schwester” (feminine), “mein Bruder” (masculine) — the ending agrees with the noun's gender and case, not with the owner.
Common mistake
Don't pick the ending based on your own gender — “mein” agrees with the gender of the thing owned, not the owner. A woman still says “mein Buch” for a neuter noun.

Does “mein” change its ending?
Yes — like “ein”, it takes endings matching the noun's gender and case: “mein”, “meine”, “meinen”, etc.
Does the ending depend on the speaker's gender?
No — it depends only on the gender/case of the noun owned, never on who is speaking.
