Questions & Answers about Hún er með svart hár.
Why does the sentence use er með instead of a word for "has"?
In Icelandic, the phrase vera með (to be with) is used instead of hafa (to have) when talking about physical characteristics, like hair or eye color, as well as things you are currently carrying or wearing.
Since we are learning about reflexives, why is there no word for "her" or "herself" here?
Why is the word for black spelled svart here instead of svartur?
Adjectives in Icelandic change to match the gender of the noun they describe. The word for hair, hár, is a neuter noun, so the adjective must be in the neuter form, which is svart. Svartur is the masculine form.
I remember that prepositions change the case of words. What case is svart hár in?
The preposition með usually makes the following words take the accusative case. For neuter words like hár and neuter adjectives like svart, the accusative form is exactly the same as the basic dictionary (nominative) form, so they don't look like they changed!
