Fjórtán

Fjórtán is the Icelandic cardinal number for fourteen. It is used when counting objects, expressing quantities, and referring to the fourteenth item or date in a sequence, among other contexts. In Icelandic, teen numbers from thirteen to nineteen are formed with a common suffix -tán on a stem derived from the digit, as in þrettán (13) and fimmtán (15); fjórtán follows this pattern, reflecting its origin as "four-ten." The word is descended from Old Norse fjörtán and is cognate with related Germanic forms in other languages.

Across the Germanic languages, cognates include Norwegian fjorten, Danish fjorten, Swedish fjorton, Dutch veertien, and German vierzehn, all meaning fourteen. In Icelandic, fjórtán is used alongside the Arabic numerals 14 in writing and speech. The number 14 is even and composite (2 × 7).
