Πετυχαίνω καλύτερο αποτέλεσμα όταν διαβάζω λίγο κάθε μέρα.

Greek often leaves out the subject pronoun because the verb ending already shows the person.

Here, πετυχαίνω means I achieve / I get, so εγώ is not necessary.

You could say Εγώ πετυχαίνω καλύτερο αποτέλεσμα..., but that would usually add emphasis, like I get a better result.

In this sentence, πετυχαίνω means something like I achieve, I get, or I obtain.

So Πετυχαίνω καλύτερο αποτέλεσμα is literally I achieve a better result.

This verb can have a few related meanings in Greek depending on context, such as:

• to succeed in
• to hit
• to meet/find someone by chance

But here the meaning is clearly achieve/get a result.

Αποτέλεσμα is a neuter noun meaning result.

In this sentence, it is the direct object of πετυχαίνω, so it is in the accusative case. But for many neuter nouns in Greek, the nominative and accusative singular look the same.

So:

• nominative: το αποτέλεσμα
• accusative: το αποτέλεσμα

That is why the form does not change visibly here.

Because καλύτερο has to agree with αποτέλεσμα, which is:

• singular
• neuter
• accusative

So the adjective must also be neuter singular accusative: καλύτερο.

Compare:

• καλύτερος άνθρωπος = better person (masculine)
• καλύτερη ιδέα = better idea (feminine)
• καλύτερο αποτέλεσμα = better result (neuter)

Greek often omits the article in a general statement like this.

So Πετυχαίνω καλύτερο αποτέλεσμα means I get a better result in a general sense, not necessarily the better result.

You could also hear:

• Πετυχαίνω ένα καλύτερο αποτέλεσμα

That is possible, but it sounds a bit more like I get a better result / one better result in a more specific or countable way. The version without ένα is very natural here.

Because this sentence describes a habitual or repeated situation:

when I read a little every day, I get a better result

In Greek, όταν + present is commonly used for repeated, general, or habitual actions.

So:

• όταν διαβάζω = when(ever) I read / when I read regularly

If you were talking about a single future event, Greek would usually use the subjunctive form instead:

• όταν διαβάσω = when I read / when I have read (in the future, one occasion)

So the present tense here matches the idea of routine.

Here λίγο is functioning as an adverb, meaning a little.

It modifies διαβάζω:

• διαβάζω λίγο = I read a little / I study a little

It is not describing a noun here, so it is not acting as an adjective.

Compare:

• διαβάζω λίγο = I read a little
• λίγο βιβλίο would be ungrammatical in this sense, because if you want a small amount of book/material, Greek would express that differently

So in this sentence, think of λίγο as describing the amount of reading.

Κάθε μέρα is the normal modern Greek way to say every day.

A few points:

• κάθε means each / every
• it is followed by a singular noun
• μέρα is the everyday spoken form of ημέρα

So:

• κάθε μέρα = every day
• κάθε ημέρα = also correct, but more formal

The form μέραν is not modern standard Greek.

Because after κάθε, Greek normally uses the noun without the article.

So:

• κάθε μέρα = every day
• κάθε φορά = every time
• κάθε άνθρωπος = every person

This is just the standard pattern.

It can mean both, depending on context.

In Greek, διαβάζω often means:

• read
• study

So this sentence could be understood as:

• when I read a little every day or
• when I study a little every day

Both are possible. Context tells you which is meant more strongly.

Yes. Greek word order is more flexible than English word order.

The sentence as given is very natural:

• Πετυχαίνω καλύτερο αποτέλεσμα όταν διαβάζω λίγο κάθε μέρα.

But you could also say:

• Όταν διαβάζω λίγο κάθε μέρα, πετυχαίνω καλύτερο αποτέλεσμα.

This puts the when clause first and sounds just as natural.

You can also move things around for emphasis, but not every order sounds equally neutral. The original sentence is a very standard, natural choice.

Usually yes, but in sentences like this it often has the sense of whenever.

Because the action is habitual, this sentence really means:

• Whenever I read a little every day, I get a better result

English often just says when, but the Greek suggests a repeated pattern, not one single event.

The original sentence already sounds like a general truth, but Greek can make that feeling even stronger with context or wording.

For example:

• Πάντα πετυχαίνω καλύτερο αποτέλεσμα όταν διαβάζω λίγο κάθε μέρα. = I always get a better result when I read a little every day.

Or:

• Πετυχαίνω καλύτερα αποτελέσματα όταν διαβάζω λίγο κάθε μέρα. = I get better results when I read a little every day.

That second version changes from singular result to plural results, which can sound even more natural in some contexts.
