Written Icelandic often incorporates abbreviations to save space and simplify text. Some common abbreviations include 't.d.' for 'til dæmis' (for example), 's.s.' for 'sem sagt' (that is to say), and 'o.fl.' for 'og fleira' (and so on). Familiarizing yourself with these abbreviations will help you navigate written Icelandic more efficiently.
