Indefinite Articles in Greek grammar are crucial for learners to grasp. In Greek, the indefinite articles are equivalent to the English indefinite articles of “a” and “an”. However, they are expressed differently depending on the gender (masculine, feminine, neuter), the case (nominative, accusative, genitive, vocative) and the number (singular, plural) of the noun they accompany. There are three different indefinite articles in Greek corresponding to each gender: ένας for masculine, μία or μια for feminine, and ένα for neuter.
