"There is a black apple."
Translation:Il y a une pomme noire.
You may disagree with Duolingo's choice of examples but you can't express it that way. Please behave and be patient with the program.
For the record: a black apple is a RED apple but it is a deep dark red...black apple. They are big & delicious.
All nouns have a gender in French. Adjectives have to agree with the noun they qualify. Therefore, "noir" goes with masculine, singular nouns and "noire" with feminine, singular nouns. Note the plural forms: "noirs" and "noires", respectively.
I thought noir was one of those adjectives whose spelling stays the same irrespective of the gender??
I don't understand why we put y and a. What do they mean together and separated?
'il y a' means 'there is' or 'there are', it is an impersonal construction you should consider as a block.
"y" is a pronoun meaning "there".
