Learn Hardcore Greek: Η δουλειά με κουράζει πολύ.

Η – definite article, feminine, singular, nominative. It marks the subject noun δουλειά.
δουλειά – feminine noun, nominative singular. It is the subject of the verb (the thing that causes the tiredness).
με – unstressed object pronoun, accusative. It means me and is the direct object of the verb.
κουράζει – verb, 3rd person singular, present, active. From κουράζω = to tire (someone).
πολύ – adverb meaning a lot / very much. It modifies the verb κουράζει.

So structurally it is: The work me tires a lot → Work tires me a lot.

Why do we use the article Η before δουλειά if in English we just say “work”?

In Greek, the definite article is used much more often than in English, including with general concepts.

Η δουλειά με κουράζει πολύ.
Literally: The work tires me a lot.
Natural English: Work tires me a lot.

You normally use η δουλειά when you mean my job / work in general.
Leaving out the article (Δουλειά με κουράζει πολύ) sounds incomplete or very awkward in standard modern Greek.

So: English often drops the article with abstract/general nouns; Greek usually keeps it.

Why is it and not ?
