Eifeler Regel

The Eifel Rule is pervasive in Luxembourgish and its effects are indicated in the standard orthography. Final ⟨n⟩ or ⟨nn⟩ are often lost when followed by another consonant other than ⟨n⟩, ⟨d⟩, ⟨t⟩, ⟨z⟩ or ⟨h⟩. Compare the following examples involving the definite article den ("the"):

• den Apel ("the apple"), den Tuerm ("the tower"), but de Ball ("the ball")

Since Luxembourgish orthography strives for phonetic accuracy, the deletion of n is also reflected in writing. Now, the Eifeler Regel is presented as a spelling rule, but its correct application still depends on a knowledge of spoken Luxembourgish. The rule targets words ending in -n or -nn, and since that is an extremely common ending for verbs, plural nouns, and function words (e.g. articles, pronouns, prepositions) in Luxembourgish, its effects are widespread. The basic rule can be described as follows:[3]

• Final -n(n) is deleted before another consonant.

  (between words) den + Ball → de Ball ("the ball"), wann + mer ginn → wa mer ginn ("when we go")

  (in compound words) Dammen + Schong → Dammeschong ("women's shoes")

• It is not deleted, however:
  • before the consonants n, d, t, z, or h

    den Tuerm ("the tower"), wann hien drénkt ("when he drinks")

    Gromperenzalot ("potato salad"), fënnefandrësseg ("thirty-five")

  • before a vowel

    den Apel ("the apple"), wann ech ginn ("when I go")

    Ouerenentzündung ("ear infection")

  • at the end of a sentence or before a punctuation mark

    Ech hunn (wéi gëschter) vill geschafft. ("I have (like yesterday) done a lot of work.")

• Deletion is optional before the following function words beginning in s: säin, si/se/s', sech, seng, sou (and perhaps others).

It is important to know that many words ending in -n or -nn are not affected by the Eifeler Regel:

• proper nouns: Schuman, Johann, München
• loanwords: Roman, Maschin(n), nouns ending in -ioun
• the prefix on-: onvergiesslech ("unforgettable")
• most nouns and adjectives (for historical reasons): Mann (man), dënn (thin), Kroun (crown), Loun (salary), blann (blind), Reen (rain), …

In fact, n as a stem consonant (as opposed to part of a grammatical ending) is generally stable in content words, with notable exceptions such as Wäi(n) (wine), Stee(n) (stone), geschwë(nn) (soon).

When final -n is dropped from a plural noun whose singular form also ends in -e (which occurs mostly in loanwords), a diaeresis must be used to distinguish the plural:

• Chance (singular [ˈʃɑ̃ːs]), Chancen (plural, full form [ˈʃɑ̃ːsən]), Chancë (plural + Eifel Rule [ˈʃɑ̃ːsə])

In Colognian, the Eifeler Regel is of lesser impact than further south. This is due in part to slight morphological differences between the Moselle Franconian languages of the upper Eifel regions (High Eifel and Schneifel), and the Ripuarian languages of the North- and Vordereifel region and the Cologne Lowland, to which Colognian belongs.

There are several ways to write Colognian, and the Eifeler Regel may be reflected in writing when it follows phonetic reality, but more often is not, since the majority of people do not write very phonetically.

In comparison to standard German, Colognian is often described as having historically omitted the trailing n. This is oversimplified, and not always true, but makes it necessary to note that the Colognian version of liaison sometimes inserts an n. In fact, Colognian multisyllabic base words or lexemes regularly drop "-n" when related languages, such as Standard German and neighboring dialects to the North such as Low German, Dutch and Limburgish do not. Liaison is often optional, and there is hardly any liaison on stressed words within a sentence. For example, with the words bovve (up, up there) and en (in, into), one may build the phrase: bovve en der Schaaf (up there into the cupboard) which depending on stress and voice flow inside a complete sentence is spoken as either [ˈbɔvə ʔen dɐ ˈʃaˑf] or [ˈbɔvən‿en dɐ ˈʃaˑf].

The general rule is that monosyllabic words most often keep their trailing n, while otherwise -en endings are transformed to -e in Colognian unless the following word starts with a glottal stop, a dental consonant, a vocal, or an h, and neither of the two words is being stressed inside the sentence.[4] There are exceptions, the most notable being that speakers do not use liaison even if they could when speaking very slowly or solemnly, e.g. preaching or praying.
