Learn Hardcore Greek: Η δουλειά είναι εδώ τώρα.

Η is the feminine singular definite article, meaning the. It’s pronounced like English “ee” [i], not like the English H sound.
Don’t confuse Η (article) with ή/Ή (the conjunction meaning or). The conjunction has an accent; the article never does.

How do I pronounce the whole sentence naturally?

IPA: [i ðuˈlja ˈine eˈðo ˈtora]
Rough guide: “ee dhou-LYÁ EE-neh eh-DHÓ TÓ-ra”
- δ = voiced “th” as in “this.”
- ου = “oo,” ει = “ee.”
- δουλειά sounds like “dhou-LYÁ” (the λ + ια creates a “lya” sound).
- Stress the syllables in caps.

Why is the article feminine (η)? How do I know that δουλειά is feminine?

Could I omit the article and just say δουλειά είναι εδώ τώρα?

That sounds odd. Without an article, it reads like “Work is here now” in a generic or unnatural way.
If you mean “a job is here now,” say Μια δουλειά είναι εδώ τώρα.
Often, existence is expressed with υπάρχει: Υπάρχει δουλειά εδώ τώρα (“There is work here now”).

Is the word order fixed? Can I say Τώρα η δουλειά είναι εδώ or Η δουλειά είναι τώρα εδώ?

Greek word order is flexible. All of these are grammatical.
Moving τώρα or εδώ changes emphasis slightly: the element placed later often gets more focus.

Why isn’t there an “it” in the sentence? Should I add αυτό?

Greek is a pro-drop language; you don’t need a subject pronoun. Η δουλειά itself is the subject.
Αυτό είναι εδώ τώρα means “This is here now,” which is different.

What form of “to be” is είναι? Does it also mean “are”?

How do I make it negative?

Put δεν before the verb: Η δουλειά δεν είναι εδώ τώρα (“The work is not here now”).

Can I put εδώ at the front: Εδώ είναι η δουλειά τώρα?

Yes. Εδώ είναι η δουλειά τώρα front-loads the place (“Here is where the work is now”), highlighting location.

Any spelling traps with δουλειά?

Don’t confuse δουλειά (“work, job”) with δουλεία (“slavery”). The difference is the stress:
- δουλειά (stress on the last syllable: -λιά)
- δουλεία (stress on -λε-ία)

Does δουλειά mean both “work” and “job”? Are there synonyms?

Yes. δουλειά can mean “work” (activity) or “job” (employment/task).
More formal εργασία = “work/labor” (official, academic contexts).
Colloquially, δουλειές can mean “errands/chores” (e.g., Έχω δουλειές = “I have errands”).

Is it okay to have both εδώ and τώρα together? Which order is more natural?

Yes, both can co-occur. Common patterns: … είναι εδώ τώρα or … είναι τώρα εδώ.
Place the one you want to emphasize later in the sentence.

How do I say “My job is here now”?

What case is δουλειά here? How does it change in other cases?

Is the lack of an accent on the initial Η correct?

Yes. The article η/Η never takes an accent. The accented one ή/Ή is the conjunction or, which is a different word.
