Questions & Answers about Þetta er bók og hún er hér.
Why use hún for a book? Doesn't hún mean "she"?
Yes, hún means "she", but Icelandic uses grammatical gender for all nouns. Because bók is a feminine word, you must use the feminine pronoun hún when referring back to it, even though we translate it as "it" in English.
Why does the sentence start with þetta instead of a feminine word if bók is feminine?
I see the word er twice. Which pronouns does it go with?
Where is the word for "a" in "a book"?
Icelandic doesn't have a separate word for "a" or "an". The word bók on its own translates perfectly to "a book".
