Αυτή την εποχή προσπαθώ να κοιμάμαι νωρίς, γιατί έχω πολλή δουλειά.

Because this phrase is being used adverbially to mean at this time / these days / during this period.

In Greek, many time expressions use the accusative case, so both words change form:

• nominative: αυτή η εποχή = this season / this period as the subject
• accusative: αυτή την εποχή = this period / at this time

So in the sentence, αυτή την εποχή is not the subject. It functions as a time expression.

It means something like:

• at the moment
• these days
• currently
• during this period

It is a little broader than just now. It suggests a stretch of time, not just this exact second.

So Αυτή την εποχή προσπαθώ... means These days / At the moment, I’m trying...

Because Greek normally uses the article with nouns much more often than English does.

Here the phrase is:

• αυτή = this
• την = the (feminine accusative singular)
• εποχή = period / season / time

So Greek says literally something like this the period, but in natural English we just say this period or at this time.

The article must agree with the noun:

• η εποχή = the period
• την εποχή = the period (accusative)

And the demonstrative also agrees:

• αυτή η εποχή
• αυτή την εποχή

Because after προσπαθώ (I try), Greek normally uses να + verb.

So:

• προσπαθώ να κοιμάμαι = I try to sleep / I try to be sleeping / I try to go to bed
• not προσπαθώ κοιμάμαι

The word να introduces the following verb clause, similar to English to in try to sleep, though it does not work exactly the same way grammatically.

This is a very common pattern in Greek:

• θέλω να φύγω = I want to leave
• μπορώ να έρθω = I can come
• προσπαθώ να διαβάζω = I try to study/read

This is an important aspect difference.

• κοιμάμαι = imperfective aspect
• κοιμηθώ = perfective aspect

In this sentence, προσπαθώ να κοιμάμαι νωρίς means I’m trying to sleep/go to bed early regularly these days. It describes a habit or repeated behavior.

If you said προσπαθώ να κοιμηθώ νωρίς, it would sound more like I’m trying to fall asleep early or I’m trying to get to sleep early, often referring to a more specific attempt.

So:

• να κοιμάμαι νωρίς = trying to make it a routine / repeated pattern
• να κοιμηθώ νωρίς = trying to succeed on a particular occasion

In everyday Greek, it often means go to bed early, even though literally κοιμάμαι is sleep.

So in this sentence, the natural idea is probably:

• I’m trying to go to bed early

Depending on context, English may translate it as sleep early or go to sleep early, but go to bed early is often the most natural interpretation.

Νωρίς is an adverb, meaning early.

It modifies the verb κοιμάμαι, telling you when the action happens:

• κοιμάμαι νωρίς = I sleep / go to bed early

Because it is an adverb, it does not change form here.

Compare:

• νωρίς = early
• αργά = late

Examples:

• Ξυπνάω νωρίς. = I wake up early.
• Κοιμάται αργά. = He/She goes to bed late.

Because δουλειά is a feminine singular noun, and here πολλή is an adjective agreeing with it.

• η δουλειά = the work
• πολλή δουλειά = a lot of work

So the adjective must be feminine singular:

• masculine: πολύς
• feminine: πολλή
• neuter: πολύ

Not πολλά, because πολλά is plural/neuter and does not match δουλειά.

Also note that δουλειά here is usually treated as an uncountable idea: a lot of work, not many works.

They can be different parts of speech.

1. πολλή = adjective

It agrees with a noun.

• πολλή δουλειά = a lot of work
• πολλή ζέστη = a lot of heat

2. πολύ = adverb

It means very / a lot and modifies a verb, adjective, or another adverb.

• δουλεύω πολύ = I work a lot
• είναι πολύ κουρασμένος = he is very tired

So in your sentence:

• έχω πολλή δουλειά = I have a lot of work

But you could also say:

• δουλεύω πολύ = I work a lot

Greek often expresses this idea with have:

• έχω πολλή δουλειά = I have a lot of work

This is a very natural Greek way to explain why someone is tired, stressed, or short on time.

Of course Greek can also say I’m busy, for example:

• είμαι απασχολημένος / απασχολημένη

But έχω πολλή δουλειά is extremely common and very idiomatic.

Here γιατί means because:

• ..., γιατί έχω πολλή δουλειά. = ..., because I have a lot of work.

Yes, επειδή could also work here:

• Αυτή την εποχή προσπαθώ να κοιμάμαι νωρίς, επειδή έχω πολλή δουλειά.

Both are natural. In everyday speech, γιατί is very common.

Just remember that γιατί can also mean why in questions:

• Γιατί κοιμάσαι νωρίς; = Why do you go to bed early?

So the meaning depends on context and intonation.

The given word order is very natural, but Greek is fairly flexible.

The original sentence:

• Αυτή την εποχή προσπαθώ να κοιμάμαι νωρίς, γιατί έχω πολλή δουλειά.

works well because it starts with the time frame, then the main action, then the reason.

You could also hear variations such as:

• Προσπαθώ να κοιμάμαι νωρίς αυτή την εποχή, γιατί έχω πολλή δουλειά.
• Γιατί έχω πολλή δουλειά, αυτή την εποχή προσπαθώ να κοιμάμαι νωρίς.

These are grammatically possible, but the original version sounds the most straightforward and natural for neutral conversation.

Yes.

• προσπαθώ = I try / I am trying
• κοιμάμαι = I sleep / I am sleeping / I go to bed
• έχω = I have

In English, this sentence is often translated with a present continuous idea:

• These days I’m trying to go to bed early, because I have a lot of work.

Greek present tense often covers both simple present and present continuous, depending on context.
