   • Isaiah 40 (Icelandic, English)

     Heyr, einhver segir: "Kalla þú!" Og ég svara: "Hvað skal ég kalla?" "Allt hold er gras og allur yndisleikur þess sem blóm vallarins. Grasið visnar, blómin fölna, þegar Drottinn andar á þau. Sannlega, mennirnir eru gras. Grasið visnar, blómin fölna, en orð Guðs vors stendur stöðugt eilíflega."

     Hark, someone's voice says, "Cry out." And I said, "What shall I cry?" "All men are like grass, and all their glory is like the flowers of the field. The grass withers and the flowers fall, because the breath of the LORD blows on them. Surely the people are grass. The grass withers and the flowers fall, but the word of our God stands forever."

• This word has a peculiar style of abbreviation, which not used with any other word:

abbreviation of einhver

singular	masculine	feminine	neuter
nominative	e-r	e-r	e-ð / e-t
accusative	e-n	e-a	e-ð
dative	e-m	e-i	e-u
genitive	e-s	not used	e-s

The above abbreviation is the standard and is used in both formal and informal writing. It ubiquitous in dictionaries. It is however rarely used by younger speakers (born after ca. 1985). Instead younger speakers often either do not abbreviate this word or they use the non-standard eh or e-h (abbreviated from einhver), with eh being very widespread in online messaging, although many consider it extremely informal or simply invalid.

• There are also proscribed colloquial forms where the forms of the prefix switch between forms, especially in the neuter singular: einhvert, einhvað, eitthver, eitthverju, etc. instead of standard eitthvert, eitthvað, einhver, einhverju.
