Compound Nouns

Level 3

In Danish, compound nouns are written as one single word without spaces. The final word in the compound is the 'head'—it dictates the gender (en/et) and how the word is pluralized.

How It Works

Danish is a compounding language, meaning you can combine nouns, verbs, or adjectives to create specific new meanings.

1. The 'Last Word' Rule: The most important rule is that the final noun in the chain is the boss. It determines:

  • The noun gender: en vin (a wine) + et glas (a glass) = et vinglas (a wine glass).
  • The plural: en bil (a car) + nøgler (keys) = bilnøgler (car keys).
  • The definite form: et sommerhus (a summer house) becomes sommerhuset (the summer house).

2. Linking Elements: Words aren't always just smashed together. Sometimes they need a 'glue' called a linking element (fuge-element).

  • No linker: Common when the first word ends in a vowel (e.g., havebord - garden table).
  • Linking -s-: Often used if the first part is already a compound or ends in certain suffixes (e.g., fodboldstræner - football coach).
  • Linking -e-: Common with short, one-syllable words or specific nouns like 'barn' (e.g., hundemad - dog food, børnetøj - children's clothing).
  • Linking -er-: Often used with specific words like 'blomst' (flower), e.g., blomsterbutik (flower shop).

3. Verbs in Compounds: When a verb is the first part of a compound, we often use the full infinitive form (e.g., vaske + maskine = vaskemaskine) or sometimes the verb stem (the infinitive minus the final -e), such as springvand (fountain) from at springe.

4. Meaning Changes: Writing words together vs. apart changes the meaning. En rødvin is the specific drink 'red wine', whereas en rød vin is simply any wine that happens to be red.

  1. Jeg har købt et nyt sommerhus.

    I have bought a new summer house.

    Word by Word: I have bought a new summer-house.

    'Sommer' (summer) and 'hus' (house) combine. Since 'hus' is neuter (et), the whole compound is 'et sommerhus'.

  2. Hvor er mine bilnøgler?

    Where are my car keys?

    Word by Word: Where are my car-keys?

    'Bil' (car) and 'nøgler' (keys) combine. The plural 'nøgler' makes the whole compound plural.

  3. Han er en dygtig fodboldspiller.

    He is a talented football player.

    Word by Word: He is a talented foot-ball-player.

    This compound uses three parts: fod + bold + spiller. It is written as one word.

  4. Vi skal bruge et vinglas.

    We need a wine glass.

    Word by Word: We shall use a wine-glass.

    Even though 'vin' is common gender (en), 'glas' is neuter (et), so the compound takes 'et'.

  5. Der er meget hundemad i skålen.

    There is a lot of dog food in the bowl.

    Word by Word: There is much dog-e-food in bowl-the.

    This example shows the linking -e- (hund + e + mad).

  6. Vaskemaskinen er gået i stykker.

    The washing machine is broken.

    Word by Word: Wash-e-machine-the is gone in pieces.

    This shows the infinitive form (vaske) used as the first part of a compound.

Common Mistakes

  • Writing compound nouns as two separate words (Særskrivning).

    Jeg skal bruge en cykel hjelm.
    Jeg skal bruge en cykelhjelm.

    English speakers often put a space between the words. In Danish, if it's one concept, it must be one word. A 'cykel hjelm' would literally mean a bicycle that is also a helmet, which makes no sense.

  • Inflecting the first part of the compound.

    børnehaverbørn
    børnehavebørn

    Only the very last word in a compound should be changed for plural or definite forms. The first parts remain in their base (or linking) form.
