(and perhaps others). 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 ), Chancen (plural, full form ), Chancë (plural + Eifel Rule ) Colognian 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. The Colognian version of liaison sometimes inserts an n. Colognian multisyllabic base words or lexemes regularly drop "-n" when some related languages, such as Standard German and Low German (but not 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 (up, up there) and (in, into), one may build the phrase: (up there into the cupboard) which depending on stress and voice flow inside a complete sentence is spoken as either or . 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 vowel, or an h, and neither of the two words is being stressed inside the sentence. There are exceptions, the most notable being that speakers do not use liaison even if
