Fossilized Case Forms

Level 6

Modern Danish doesn't have a case system for nouns, but ancient remnants (fossils) survive in specific, fixed phrases. These usually involve a preposition followed by a noun ending in -e (old dative) or -s (old genitive).

How It Works

In Old Danish, prepositions 'governed' specific cases, meaning they forced the following noun into a specific form. While this system died out centuries ago, many high-frequency phrases were 'frozen' in time.

1. Dative Remnants (-e)
Historically, the dative singular for many nouns ended in -e. In modern Danish, this suffix resembles a common plural ending. However, in these fossilized phrases, the -e is a singular case marker. Note that for many of these nouns, the fossilized form does not match the modern plural (e.g., the plural of fod is fødder, not fode).

  • i live (alive) - from 'liv' (life)
  • på fode (on one's feet) - from 'fod' (foot)
  • af gårde (away/off) - from 'gård' (farm/yard)

2. Genitive Remnants (-s)
The preposition til historically governed the genitive case. While we still use possessive -s today, these fossilized versions don't show possession; they show direction or state.

  • til søs (at sea)
  • til bords (at the table/dining)
  • til fods (on foot)

3. Usage and Register
These are not 'slang' or 'old-fashioned'—many are the standard, mandatory way to express an idea. For example, you cannot say 'han er i liv'; you must say 'han er i live' to mean he is alive.

Examples (5)

  1. Patienten er stadig i live.

    The patient is still alive.

    Word by Word: The patient is still in life.

    'I live' is a fossilized dative form of 'liv'. Without the -e, the phrase would be ungrammatical in this context.

  2. Vi gik til bords klokken atten.

    We sat down to dinner at six o'clock.

    Word by Word: We went to table's clock eighteen.

    'Til bords' uses the old genitive -s. It specifically refers to the act of sitting down to eat, not just walking toward a physical table.

  3. Han kom hurtigt på fode igen efter sygdommen.

    He quickly got back on his feet after the illness.

    Word by Word: He came quickly on foot again after the illness.

    'På fode' is a dative remnant. Note that 'fode' is singular here, even though we translate it as 'feet' in English idioms.

  4. De rejste både til lands og til vands.

    They traveled both by land and by sea.

    Word by Word: They traveled both to land's and to water's.

    These are classic genitive remnants used with the preposition 'til' to describe modes of travel.

  5. Manden gik fra huse.

    The man lost his home (became homeless).

    Word by Word: The man went from house.

    'Fra huse' is an idiomatic fossil. Although 'huse' looks like the plural 'houses', it is historically a singular dative form.

Common Mistakes

  • Treating the -e ending as a plural.

    Han er på fødder.
    Han er på fode.

    While it looks plural, 'fode' is a singular dative fossil. The actual plural of 'fod' is 'fødder'. Don't try to change 'fode' to 'fødder' in this specific idiom.

  • Trying to make the fossilized noun definite.

    Vi gik til bordsen.
    Vi gik til bords.

    Fossilized forms never take the definite suffix. They are fixed units and cannot be modified.

  • Applying the endings to new nouns (Productivity Error).

    Jeg er i huse.
    Jeg er i huset.

    You cannot add -e to any noun to make it 'dative'. This only works for a small set of established historical phrases. For everything else, use standard modern grammar.

Learn This First

Dative remnants are fossilized grammatical forms from Old Danish where nouns took specific endings after certain prepositions. To understand these, you should first be familiar with basic prepositions and the modern genitive case, as these remnants appear as 'irregular' endings in common fixed phrases.
