In German
des Mannes
Meaning: “des Mannes” (of the man) — Genitiv, masculine: shows possession
Example sentences
DasAutodesMannesistneu.
The man's car is new.
DerNamedesMannesistPeter.
The man's name is Peter.
DieTaschedesMannesistschwarz.
The man's bag is black.
Grammar note
Genitiv shows possession — “of the man” or “the man's”. Masculine and neuter nouns take “des” and usually add “-s” or “-es” to the noun itself; feminine and plural take “der” with no change to the noun.
Common mistake
Don't forget the “-s” on the noun. “Des Mann” is incomplete — it must be “des Mannes”, with the noun itself taking an ending in the masculine and neuter Genitiv.

Is the Genitiv common in spoken German?
Less than the other three cases — everyday speech often replaces it with “von” plus the Dativ (“das Auto von dem Mann”), but the Genitiv is still correct and common in writing.
Do all masculine nouns add “-es” in the Genitiv?
Many short nouns add “-es” (like “Mannes”), while longer ones often just add “-s” (like “Vaters”).
