"Η ποίηση είναι μία κατηγορία της λογοτεχνίας."

Translation: Poetry is a type of literature.

[bonbayel]

I like that λογοτεχνίας means 'word art'.

[jeanprendiville]

A more usual phrase would read " poetry is a form of literature". If it is not included, you might think of adding it.

[Walt1965]

In a previous example of this sentence I wrote ´μία' and was marked wrong. This time I wrote ´μια' and was marked wrong again. Now what?
