Afleiddar

Afleiddar is an Icelandic linguistic term used to describe words or word forms that are created from a base form through derivation. Afleiddar forms are not the base lemma themselves, but new words produced by adding affixes, changing the word class, or combining elements. They help explain how a language builds related words from a common root and express different meanings or grammatical categories.

The term comes from the verb afleiða, meaning to derive, with the participle-like ending that yields the adjective afleiddar (derived). In Icelandic grammar, derivation is a productive mechanism for forming nouns, adjectives, and sometimes verbs from existing words. Common categories include afleiddar nafnorð (derived nouns) formed with suffixes such as -ari, -ung, or -un; afleiddar lýsingarorð (derived adjectives); and afleiddar sagnir (derived verbs). An example is kennari, an afleidd nafnorð meaning “teacher,” formed from the verb kenna “to teach.”

Role and usage: In dictionaries, grammar descriptions, and language teaching, afleiddar forms are analyzed to show word-formation patterns, semantics, and productivity. They also arise in computational morphology and linguistic research to classify how words are built and how derivational processes interact with inflection.

Because Icelandic has a rich system of derivation, afleiddar forms constitute a substantial portion of everyday vocabulary, enabling nuanced expression through systematic word formation.
