Φοβάμαι μην χάσουμε τη σωστή διασταύρωση, γιατί ο χάρτης στο κινητό δεν δουλεύει καλά.

After φοβάμαι when you mean I’m afraid that... / I’m worried that..., Greek very often uses μη(ν) + the subjunctive.

So:

• Φοβάμαι μην χάσουμε... = I’m afraid we might miss...
• Literally, it is something like I fear lest we miss...

This is a very common Greek structure.
It does not mean simple negation here. In this sentence, μην introduces the feared possibility.

A useful pattern to remember is:

• Φοβάμαι μην + subjunctive

For example:

• Φοβάμαι μην αργήσουμε. = I’m afraid we’ll be late.

Χάσουμε is the aorist subjunctive of χάνω (to lose, to miss).

Here it means:

• that we might miss
• that we may miss

It is formed with the aorist stem χασ- plus the subjunctive ending.

In this sentence, it appears without να because after φοβάμαι μην, Greek normally uses μην instead of να.

So:

• μην χάσουμε = that we might miss

Because Greek is focusing on a single possible event: missing the correct intersection once.

Compare:

• χάσουμε = miss as one complete event
• χάνουμε = we are missing / we miss in a more ongoing or habitual sense

In this sentence, the speaker is worried about one specific moment during the trip, so the aorist subjunctive is the natural choice:

• Φοβάμαι μην χάσουμε τη σωστή διασταύρωση.

If you used χάνουμε, it would sound less natural here because the idea is not continuous action but one possible mistake at one point on the route.

Because Greek verb endings already show the subject.

χάσουμε means we may miss / we might miss, so the we is built into the verb form.

Greek often drops subject pronouns when they are not needed.
So:

• χάσουμε already tells you it is we
• adding εμείς would only be for emphasis

For example:

• Φοβάμαι μην χάσουμε... = normal
• Φοβάμαι μην εμείς χάσουμε... = unusual unless you are contrasting we with someone else

It means the correct intersection/junction.

Breakdown:

• τη = the (feminine accusative singular)
• σωστή = correct/right
• διασταύρωση = intersection, junction, crossroads

So the whole phrase is the direct object of χάσουμε:

• χάσουμε τη σωστή διασταύρωση = miss the correct intersection

In travel contexts, διασταύρωση usually refers to a road intersection or junction.

Both τη and την are used in modern Greek as the feminine accusative singular article.

• την is the full form
• τη is a very common shortened form before many consonants in everyday speech and writing

So both of these are possible:

• τη σωστή διασταύρωση
• την σωστή διασταύρωση

The shorter τη is very normal and natural.

Usually yes, in this context διασταύρωση is best translated as intersection or junction.

Depending on context, it can refer to:

• roads crossing
• a turning point where routes split or meet
• a junction in general

So if someone is using GPS or directions, διασταύρωση is exactly the kind of word you would expect.

Στο κινητό literally means on the mobile phone or on the cellphone.

It is made of:

• σε = in / at / on
• το = the

These combine into:

• σε + το = στο

So:

• ο χάρτης στο κινητό = the map on the phone

Greek often uses this kind of phrase where English also says on the phone.

Because χάρτης is a masculine noun in Greek.

So its basic form is:

• ο χάρτης = the map

This is why the sentence says:

• ο χάρτης στο κινητό

If you are learning noun gender, this is something you simply have to memorize with the noun:

• χάρτης → masculine

Yes. Δεν δουλεύει καλά is very natural Greek and means:

• isn’t working well
• doesn’t work properly

Even though δουλεύω literally means to work, Greek uses it very broadly for machines, devices, software, apps, and systems.

So:

• Ο χάρτης στο κινητό δεν δουλεύει καλά. = The map on the phone isn’t working well.

You might also hear:

• δεν λειτουργεί καλά = it doesn’t function well

That version is a bit more formal.
δεν δουλεύει καλά is extremely common in everyday speech.

Here γιατί means because and introduces the reason.

So the sentence structure is:

• Φοβάμαι μην χάσουμε τη σωστή διασταύρωση = main idea
• γιατί ο χάρτης στο κινητό δεν δουλεύει καλά = reason

In English:

• I’m afraid we might miss the right intersection, because the map on the phone isn’t working well.

Be careful: γιατί can also mean why in questions.

For example:

• Γιατί αργείς; = Why are you late?
• Αργώ γιατί έχει κίνηση. = I’m late because there is traffic.

Yes, Greek word order is more flexible than English, though some orders sound more neutral than others.

The given sentence is very natural:

• Φοβάμαι μην χάσουμε τη σωστή διασταύρωση, γιατί ο χάρτης στο κινητό δεν δουλεύει καλά.

You could also say:

• Γιατί ο χάρτης στο κινητό δεν δουλεύει καλά, φοβάμαι μην χάσουμε τη σωστή διασταύρωση.

That is still understandable, but it sounds more marked or stylistically different.
The original order is the most natural for everyday speech.

A rough pronunciation guide is:

• Φοβάμαι → vo-VA-me
• μην → min
• χάσουμε → HA-su-me
• τη σωστή → ti so-STI
• διασταύρωση → thia-sta-VRO-si
• γιατί → ya-TI
• ο χάρτης → o HAR-tis
• στο κινητό → sto kini-TO
• δεν δουλεύει καλά → then thu-LE-vi ka-LA

A few sound notes:

• φ sounds like English f
• χ before α sounds like a harsher sound, roughly like the ch in Scottish loch
• δ in δεν sounds like th in this
• θ in διασταύρωση sounds like th in thin

In this exact structure, μην is the normal choice:

• Φοβάμαι μην χάσουμε...

Using να here would not be the standard way to express this fear.
The pattern is specifically tied to the idea of fearing that something bad may happen.

So for learners, it is best to memorize it as a chunk:

• φοβάμαι μην...

That will sound much more natural than trying to build it with να.

It is neutral, everyday modern Greek.

Nothing in it is especially formal or slangy:

• Φοβάμαι μην... = normal
• τη σωστή διασταύρωση = normal
• ο χάρτης στο κινητό = normal
• δεν δουλεύει καλά = everyday spoken Greek

So this is exactly the kind of sentence you might hear in real life while driving or walking with GPS.
