In Icelandic, common nouns (samheiti) are used to signify general items rather than specific ones. They are extremely essential to everyday vocabulary, encompassing objects, persons, places, and things. They can be very broad, such as “bók” (book), or more specific, like “hundur” (dog). However, they do not refer to a specific book or a specific dog, but rather any book or any dog in general. Learning to effectively use and understand these common nouns can significantly expand a student’s abilities to communicate and understand written and spoken Icelandic.
