Ylhýra’s inflection tables are from the The Database of Icelandic Morphology (better known as BÍN) by the Árni Magnússon Institute for Icelandic Studies. The author and editor of the database is Kristín Bjarnadóttir.

Ylhýra only shows inflection examples that are considered to be standard Icelandic. Non-standard and colloquial inflections can be found by searching BÍN.

BÍN’s original inflection forms are shown, with the addition of helper words and highlights of irregular inflections.
