Απορώ πώς μπορεί να μένει τόσο αδιάφορη, όταν όλοι οι άλλοι ανησυχούν.

Απορώ literally means I am puzzled, I find it hard to understand, or I wonder.

In this sentence, it does not mean that the speaker is asking a direct question. It expresses a feeling of surprise or disbelief:

• Απορώ = I can’t understand / I’m amazed / I wonder

So the speaker is saying that they find the woman’s reaction hard to understand.

Here πώς means how, and it introduces an indirect question:

• Απορώ πώς... = I wonder how... / I can’t understand how...

Greek often uses πώς after verbs like απορώ, βλέπω, ξέρω, θυμάμαι when the speaker is referring to how something happens.

So:

• Απορώ πώς μπορεί να μένει τόσο αδιάφορη
  = I wonder how she can remain so indifferent

This is different from ότι, which would introduce a statement, not an indirect how-question.

The accent helps distinguish πώς (how) from πως, which can sometimes mean that in less formal writing.

So here:

• πώς = how

In modern Greek, people do not always make this distinction consistently in casual writing, but in careful writing the accent is useful.

μπορεί να often means can, is able to, or sometimes may / might depending on context.

Here:

• μπορεί να μένει = can remain / be able to remain

Using μπορεί adds the idea of amazement that this is even possible:

• Απορώ πώς μένει τόσο αδιάφορη = I wonder how she remains so indifferent
• Απορώ πώς μπορεί να μένει τόσο αδιάφορη = I wonder how she can remain so indifferent

The version with μπορεί sounds stronger: the speaker is surprised that such a thing is possible.

This is a question of aspect.

• να μένει = imperfective
• να μείνει = perfective

Here μένει describes an ongoing state: remaining, staying indifferent over a period of time.

So:

• να μένει τόσο αδιάφορη = to keep remaining / to stay so indifferent

If you used να μείνει, it would sound more like a single event or a completed reaction: to become/remain indifferent at one point. That is not the main idea here.

Because the sentence describes a continuing attitude while others are worried, the imperfective form μένει is the natural choice.

αδιάφορη is a predicate adjective agreeing with the implied subject, which is she.

Greek adjectives agree in:

• gender
• number
• case

Here the subject is omitted, but understood from context. The sentence is talking about a woman, so the adjective is feminine singular:

• masculine: αδιάφορος
• feminine: αδιάφορη
• neuter: αδιάφορο

So μένει τόσο αδιάφορη means she remains so indifferent.

Greek often drops subject pronouns because the verb form already shows the person and number, and the context gives the rest.

In this sentence, the person being described is understood from context, so Greek does not need to say αυτή.

That is very normal in Greek:

• μένει = she/he stays
• ανησυχούν = they worry / are worried

Greek uses explicit subject pronouns mostly for emphasis, contrast, or clarity.

τόσο means so, so much, or to such a degree.

In this sentence:

• τόσο αδιάφορη = so indifferent

It intensifies the adjective αδιάφορη.

Compare:

• αδιάφορη = indifferent
• τόσο αδιάφορη = so indifferent

Yes. μένω + adjective is a very common Greek pattern meaning remain/stay + adjective.

So:

• μένει αδιάφορη = she remains indifferent
• μένει ήρεμη = she remains calm
• μένει σιωπηλός = he remains silent

This is a normal and natural structure in Greek.

όταν means when or while, depending on context.

In this sentence, it is best understood as when / while:

• όταν όλοι οι άλλοι ανησυχούν
  = when / while all the others are worried

The idea is that her indifference contrasts with the fact that everyone else is worried at the same time.

So όταν introduces the background situation against which the speaker is reacting.

ανησυχούν is present tense because it describes what the others are doing or feeling at that same time:

• ανησυχούν = they are worried / they worry

Greek present tense often covers both:

• a general present
• an ongoing present situation

Here it describes a current, ongoing state: the others are worrying, while she remains indifferent.

όλοι οι άλλοι means all the others.

It is made up of:

• όλοι = all
• οι άλλοι = the others

Together they mean everyone else or all the others.

Greek often uses the article with άλλοι:

• οι άλλοι = the others

So the phrase is completely natural.

The comma separates the main clause from the subordinate clause:

• Απορώ πώς μπορεί να μένει τόσο αδιάφορη,
• όταν όλοι οι άλλοι ανησυχούν.

The second clause gives the circumstance or contrast that makes the speaker puzzled.

Greek punctuation often uses commas in places similar to English, especially before a subordinate clause that adds explanatory context like this.

Yes. Greek word order is more flexible than English, though not completely free.

The given order is natural and clear:

• Απορώ πώς μπορεί να μένει τόσο αδιάφορη, όταν όλοι οι άλλοι ανησυχούν.

But some parts could move for emphasis. For example, Greek could emphasize τόσο αδιάφορη or όλοι οι άλλοι in other contexts.

Still, the original order is the most neutral and natural for this sentence.

Both can work, depending on how natural you want the English to sound.

• ανησυχούν literally corresponds to they worry / they are worrying
• in natural English here, are worried is often better

So:

• όταν όλοι οι άλλοι ανησυχούν
  can be understood as
  when everyone else is worried

Greek often uses verbs where English may prefer an adjective or participle-like expression.
