eins, zwei, drei. Ich habe ein Buch. Er hat auch eins. Sie wird eines Tages eins haben. Meine Schwester hat eine Eins in Mathe. Seriously, German? Sometimes I think this language is simply designed to confuse people. Eins? Eines? Eine? Eine Eins? Huh? 

Hallo, Deutschlerner! Today, we’re diving into a topic that often confuses my students in German 1 and 2: the difference between “eins” and “eines.” So, grab your notebooks and let’s unravel this linguistic mystery together.

  • “eins” and “eines” translate to “one”
  • usage varies on context. 
  • “Eins” is the cardinal number – counting or stating a quantity
  • “ein” is an article – used to say “a” or “one” followed by a noun 
  • sometimes this article is used as a kind of pronoun = no noun behind it
  • endings on “ein” depend on a variety of factors
    • case & gender of noun that follows
    • if no noun is present, this version of the chart is used
      • differences in the nominative & accusative = masculine – einer, neuter – eins
    • all of this means there are 4 places to use “eines” and 2 for “eins”
      • masculine or neuter in the genitive case with or without a noun all use “eines” (total 4)
      • neuter nominative or accusative without a noun use “eins” (total 2)

When to use “eins”

  • Wie spät ist es? Es ist um eins. – What time is it? It is one. (cardinal number) (Caution: Es ist ein Uhr.) 
  • Wie viele Pferde hast du? Ich habe eins. – How many horses do you have? I have one. (refers back to the neuter noun “Pferd”, but doesn’t have the noun there.)
  • Wer braucht das Arbeitsblatt? Ich habe schon eins. – Who needs the worksheet? I already have one. (refers back to the neuter noun “Arbeitsblatt”, but doesn’t have the noun there.) 
  • Sie hat fast immer eine Eins in der Schule. – She almost always has a one in school (German grade for an A) (used as a noun, but still the cardinal number)

When to use “eines”

  • Das ist für die Entwicklung eines Kindes sehr wichtig. – That is very important for the development of a child. (genitive case with a neuter noun showing possession)
  • Eines Tages kommt ein Prinz und rettet Rapunzel. – One day a prince comes and rescues Rapunzel. (genitive case with a masculine noun for indefinite time)

When to use “ein”

  • Ein Mann/Eine Frau ist ins Zimmer gekommen. – A man came into the room. (nominative followed by a masculine noun)
  • Ein Pferd gehört nicht im Aufzug. – A horse does not belong in an elevator. (nominative followed by a neuter noun)
  • Ich kaufe morgen ein neues Bett. – I am buying a new bed tomorrow. (accusative followed by a neuter noun)
