-e-

1. A morph interjected between word roots to give pronunciation a better sense of flow, but which gives no change in meaning.

• fuge-e

Originally often represented a thematic vowel or a (genitive) case ending; also sometimes added simply for ease of pronunciation. This etymology is incomplete. You can help Wiktionary by elaborating on the origins of this term.

1. a linking vowel added in compound words

   willekeur

   Koninginnedag

• -en-
• -s-

From Proto-Finnic *-dë-.

-e-

1. The second infinitive marker.

• In the active, attaches to the same stem as the first infinitive (by replacing the final -a or -ä). In the passive, attaches to the strong passive stem (same as the passive conditional without the final -isiin) and does not replace the final -a or -ä.
• Always followed by a case marker: in standard Finnish, either the inessive or the instructive case (the latter for active only).

1. used to link elements in some compounds

• IPA^(key): [ɛ]

-e-

1. A suffix-initial vowel (or linking vowel) inserted interconsonantally between the word stem and the suffix, to ease pronunciation, without contributing to the meaning.

• -ar- (in older standards when the first element is strong feminine)
• -a-

From the Old Norse genitive plural ending, -a, such as in manna mál (> mannemål). Also from the strong feminine genitive singular, -ar, whence also -ar- and -a-.

-e-

1. Genitival interfix indicating that the former element is a characteristic of the latter.

   ‎hest (“horse”) + ‎hov (“hoof”) → ‎hestehov (“horse’s hoof”)

This interfix is often used in compounds where the first element is plural, as opposed to singular -s-. Example: gudetru (“polytheism, belief in gods”) and gudstru (“monotheism, belief in a god”).

Akin to German -n-/-e-, Dutch -en-/-e- and Swedish -e-.

• IPA^(key): /-ə-/

-e-

   ‎Múus (“mouse”) + ‎Buk (“male animal”) → ‎Muzebuk (“male mouse”)

• IPA^(key): /ɛ/

-e-

1. Interfix used to link elements in some compounds

• The interfix -e- is sometimes used in compounds where the first element ends in -a:
  • This is especially productive when the word is the second element in a longer compound, e.g. högskola (“university”) → högskoleexamen (“university degree”); kolgruva (“coal mine”) → kolgruvearbetare (“coal mine worker”).
  • It is also used in shorter compounds when the first element ends in the female suffixes -inna or -erska, e.g. hjältinna (“heroïne”) → hjältinneroll (“part as a heroïne”); sköterska (“nurse”) → sköterskedräkt (“nurse’s uniform”).
  • It is also used for nouns ending in -ja or -ia, e.g. olja (“oil”) → oljeplattform (“oil rig”), historia (“history”) → historielektion (“history lesson”).
  • It is also used for some nouns ending in a consonant + /l r n/ + -a, e.g. ödla (“lizard”) → ödleart (“lizard species”); åsna (“donkey”) → åsneföl (“donkey’s foal”).
  • It is also used in some compounds of words ending in -a, e.g. ära (“honor”) → ärekränka (“defame”); hjärta (“heart”) → hjärtesorg (“grief, heartache”).
• It is also used in some compounds ending in a consonant, e.g. natt (“night”) → nattetid (“(during) nighttime”); skörd (“harvest”) → skördetröska (“combine harvester”); tjänst (“service”) → tjänsteman (“civil servant”); tid (“time”) → tideräkning (“chronology”).
• In some cases, -e- is found in more literary or archaic compounds, but not otherwise, e.g. stjärna (“star”) → stjärnevalv (“stellar vault”), cf. stjärnkikare (“astronomical telescope”)
• The interfix -e- is also more common in southern and western dialects, and thus in compounds derived from those dialects, cf. -a-, e.g. spettekaka (“skewer cake”), pilevall (“avenue of willow trees”).
