This is the 441st most frequent Icelandic word.
einar
The Icelandic word "einar" is the plural form of "einn," meaning "ones" or "solitary" depending on context. It can also be a masculine given name.
In this sentence, 'Einar' is a proper noun, a personal name commonly used in Icelandic.
Einar er að fara til Reykjavíkur.
Einar is going to Reykjavik.
Here, 'einar' is used as a determinant meaning 'some,' modifying the plural noun 'bækur' (books).
Ég kaupi einar bækur á hverjum mánuði.
I buy some books every month.
In this instance, 'Einar' functions again as a proper noun and represents a specific person's name.
