The Eifeler Regel (Eifel Rule) is a phenomenon which was originally documented in the linguistics of the late 19th century for the dialects of the Eifel region in the far west of Germany, hence the name, but it is a phenomenon, more generally called n-apocope, that pertains in varying extents to all dialects of the Western group of High German, such as West Central German (notably Luxembourgish, Colognian and Hessian), High Franconian and Alemannic; and excludes all dialects of the Eastern group, such Austro-Bavarian, the colonial dialects East of the Elbe-Saale line (including Standard German and Yiddish). N-apocope is a linguistic change originating in speech during the Middle High German period.
The rule describes a phonological process in the languages which causes the deletion of final [n] in certain contexts. It varies somewhat between languages and varieties. Also its reflection in spellings differs.
West Central German
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, but not if this consonant is ⟨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, this deletion of n is also reflected in writing. Nowadays 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 this 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:
- 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 ("35")
- 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")
- many 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, a diaeresis must be used to distinguish the plural:
- Chance (singular), Chancen (plural, full form), Chancë (plural + Eifel Rule)
In Colognian, the Eifeler Regel is of lesser impact than further south. This is 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.
Since there are several ways to write Colognian, the Eifeler Regel may reflect in writing when it follows phonetic reality, but more often does not, since the majority does not write very phonetically.
Colognian is often described saying that, in comparison to standard German, trailing n were always omitted. This is not always true and oversimplified, but makes it necessessary to note that the Colognian version of liaison sometimes inserts an n. As a matter of 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 ˈbɔ̯vən‿en‿dɐ̯‿ˈʃaˑf ˈbɔ̯və‿ⁿ‿en‿dɐ̯‿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 word is being stressed inside the sentence. 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.
High Franconian is a transitional dialect group between the Rhine Franconian dialects of West Central German to the North and the Swabian dialects of Alemannic to the South. The High Franconian group divides into South Franconian and East Franconian. N-apopcope can be documented in the following sentence from Standard German:
- Die Kinder halte-n die Äpfel fest. "The chidren hold on to the appels."
The comparison with the above mentioned dialects demonstrates:
- Rhine Franconian: Die Kinner halte die Äppel fescht.
- South Frankonian: Die Kinner halte die Äpfel fescht.
- East Frankonaian: Die Kinner halte die Äpfel fest.
- Swabian: Die Kinner haltet die Äpfel fescht.
The Eifeler Regel (Alemannic n-apocope) applies in all variants of Alemannic in the same fashion as described for Luxembourgish and is subject to the same exceptions. The earliest report on the phenomenon in Alemannic goes back to 1881.
Certain southern and southeastern dialects of Low Franconian (that is, Dutch) also have a similar phenomenon. It is notable in Limburgish and some areas of Brabantian, and is called the "bdht-vowel-rule". Final -n is also deleted in these dialects, except when followed by b, d, h, t or a vowel. This is similar to the Eifeler regel.
