What is the word for in Greek Language?

There isn't one single word in Greek that translates perfectly to the English "the." Greek uses definite articles, which change depending on the gender, number, and case of the noun they modify.

The most common definite articles are:

* ὁ (ho): masculine nominative singular

* ἡ (hē): feminine nominative singular

* τό (to): neuter nominative singular

And there are many more variations for other cases (genitive, dative, accusative) and numbers (plural).
