Questions & Answers about Katten har et grønt øje.
Why is 'the cat' written as one word, Katten?
In Danish, the word for 'the' is usually attached to the end of the noun as a suffix. Because kat is a common gender word (an en-word), you add -en to the end to make Katten.
Why does grønt end in a -t here?
Adjectives in Danish have to match the gender of the noun they describe. Because øje is a neuter noun (an et-word), you must add a -t to the base adjective grøn, making it grønt.
How do I know if øje is a common gender or neuter gender noun?
The sentence gives you two big clues! The word for 'a' is et, and the adjective grønt has the neuter -t ending. Both of these tell you that øje is a neuter noun.
If the cat had two green eyes, would I just add an -s to øje?
No, plurals are different in Danish. Øje has an irregular plural form, which is øjne. The adjective also changes in the plural by adding an -e, so 'two green eyes' would be to grønne øjne.
