Questions & Answers about Hér er ein appelsína.
Why do we use ein here instead of the standard dictionary word einn?
How can I tell that appelsína is a feminine word?
Could ein appelsína also mean "an orange"?
Yes! Icelandic does not have a separate word for "a" or "an". Depending on the context, Hér er ein appelsína can mean "Here is ONE orange" or simply "Here is an orange".
If there were two oranges, would the number two also have a special feminine form?
It sure would. In Icelandic, the numbers 1, 2, 3, and 4 all change forms to match the gender of the noun. The feminine form of two is tvær, so "two oranges" would be tvær appelsínur.
