þekktast
þekktast is the superlative form of the Icelandic adjective "þekktur," meaning "known." Therefore, "þekktast" translates to "most known" or "best known." It is used to describe the person, thing, or concept that has the widest recognition or is most familiar among a group. For example, one might say "Hún er þekktast í sínum hópi" meaning "She is the most known in her group." The word's grammatical form changes depending on the gender and number of the noun it modifies, although in its base superlative form, it often appears as "þekktastur" for masculine singular, "þekktust" for feminine singular, and "þekktustu" for plural. Understanding this superlative form is crucial for accurate comprehension and expression in Icelandic when discussing degrees of familiarity or fame.
