blíi

Blóði is the dative singular form of the Icelandic noun blóð, which means blood. Icelandic nouns decline for case and number, so the base form blóð appears in various cases as blóð (nominative/accusative), blóðs (genitive), and blóðið (definite singular). The dative singular, used after certain prepositions and in specific idioms, is blóði. In practice, blóð refers to the circulating fluid in humans and other animals, and it is a common term across medical, biological, and everyday language.

Etymology and relatives: blóð originates from Old Norse blóð and is cognate with related Germanic words such as English blood and German Blut. The Icelandic form reflects the historic Germanic declension patterns and has been retained in modern usage with its case forms.

Usage and compounds: In contemporary Icelandic, blóð serves as the root for many compounds related to circulatory biology and medical contexts, such as blóðbanki (blood bank) and blóðrás (blood circulation). The word also appears in literature, poetry, and religious or ceremonial language where images of blood carry symbolic meaning. Grammatical accuracy in Icelandic requires selecting the appropriate case form (blóð, blóðið, blóði, blóðs) according to the syntactic role in the sentence, making blóði an example of how case governs word endings in the language.
