leiðst

leiðst is not a standalone dictionary headword in modern Icelandic. It is primarily encountered as an inflected form rather than as an independently listed lemma, and in standard reference works it is not treated as a common entry. In practice, if you encounter the form it is usually part of a larger verb paradigm or a dialectal/archaic text, rather than a common modern usage.

Linguistic discussion around þess form notes that it can be connected to the broader verbal system based on the stem related to leiða (to lead) or leið (way), with suffixes that produce participial or reflexive forms in older or dialectal texts. Because Icelandic verbs exhibit rich inflection and dialectal variation, forms like leiðst may appear in some historical writings or in regional varieties, but they do not form a standard, widely used base form in contemporary Icelandic.

In contemporary Icelandic, more common related forms are used instead. The verb to lead is leda, with the past participle leiddur (led) and the passive constructions built around that form. The present tense form that commonly causes confusion is leiðist, as in mér leiðist (I am bored). The distinction between these standard forms—leiddur, leiðist, and related words—helps readers interpret texts where a form like leiðst might appear as an obsolete, dialectal, or erroneous rendering.

Summary: leiðst is not a standard modern lemma in Icelandic. It is typically understood as an inflected form found in specific contexts rather than a freely used verb form, and readers are advised to consider nearby standard forms such as leiðist or leiddur when interpreting texts.
