Δεν βρίσκω το εργαλείο και δεν μπορώ να ξεβιδώσω τη βίδα.

Because each verb is negated separately.

• Δεν βρίσκω το εργαλείο = I can’t find the tool
• και δεν μπορώ να ξεβιδώσω τη βίδα = and I can’t unscrew the screw

In Greek, if you have two coordinated clauses and both are negative, you normally repeat δεν before each finite verb. English sometimes does this too: I can’t find the tool and I can’t unscrew the screw.

Βρίσκω means I find or I am finding, but in this context it is usually understood as I can’t find / I’m not finding.

So:

• βρίσκω = I find
• δεν βρίσκω = I do not find / I can’t find

Greek often uses the present tense in places where English may prefer can’t find.

Greek uses the definite article much more often than English.

• το εργαλείο = the tool

In English, you might sometimes say I can’t find a tool or I can’t find the tool, depending on context. In Greek, if a specific tool is meant, the article is very natural and usually required.

Here, το is the neuter singular accusative/nominative article, matching εργαλείο, which is a neuter noun.

It is in the accusative case, because it is the direct object of βρίσκω.

• βρίσκω = I find
• what do I find? → το εργαλείο

For neuter nouns like εργαλείο, the nominative and accusative forms are often the same, so the form does not change here.

Both are possible in Greek spelling, but τη βίδα is the usual form before a consonant.

The full form of the feminine accusative singular article is την, but the final -ν is often dropped before many consonants in everyday usage:

• την πόρτα / τη πόρτα
• την βίδα / τη βίδα

In standard modern usage, τη βίδα is very common and natural.

μπορώ να means I can or I am able to.

• μπορώ = I can
• να introduces the following verb

So:

• μπορώ να ξεβιδώσω = I can unscrew
• δεν μπορώ να ξεβιδώσω = I can’t unscrew

A very common Greek pattern is:

• μπορώ να + verb

Because Greek normally uses να to introduce this kind of subordinate verb form.

After verbs like μπορώ (I can), θέλω (I want), πρέπει (I must), Greek uses:

• να + verb

Examples:

• Θέλω να φύγω. = I want to leave.
• Μπορώ να έρθω. = I can come.

So να often corresponds to English to, though it does not work exactly the same way in every sentence.

This is a very common learner question. Greek often distinguishes between:

• an imperfective form: ongoing, repeated, general action
• a perfective form: single, complete action

Here:

• ξεβιδώνω = I unscrew / I am unscrewing (imperfective)
• ξεβιδώσω = perfective form used after να

In δεν μπορώ να ξεβιδώσω τη βίδα, the speaker means I can’t get the screw unscrewed / I can’t unscrew the screw as a complete action. That is why the perfective form ξεβιδώσω is used.

The prefix ξε- often gives the idea of undoing, removing, or taking apart.

• βιδώνω = I screw in / fasten with a screw
• ξεβιδώνω / ξεβιδώσω = I unscrew

So ξε- here has the sense of reversing the action.

Yes, βίδα means screw as the object used in fastening things.

So:

• τη βίδα = the screw

This sentence is very practical, mechanical vocabulary:

• εργαλείο = tool
• βίδα = screw
• ξεβιδώνω / ξεβιδώσω = unscrew

The word order is quite close to English:

• Δεν βρίσκω το εργαλείο
• και δεν μπορώ να ξεβιδώσω τη βίδα

Literally:

• Not I-find the tool and not I-can to unscrew the screw

A more natural English rendering:

• I can’t find the tool and I can’t unscrew the screw.

Greek word order is somewhat flexible, but this sentence uses a very neutral, standard order.

Yes, but it is usually omitted unless you want emphasis.

Greek normally drops subject pronouns because the verb ending already shows the person:

• βρίσκω = I find
• μπορώ = I can

So the sentence does not need εγώ.

If you add it, it sounds more emphatic:

• Εγώ δεν βρίσκω το εργαλείο... = I can’t find the tool... / As for me, I can’t find the tool...

It is pronounced roughly er-ga-LEE-o.

A few notes:

• The stress is on -λεί-
• The ending -είο is pronounced with two vowel sounds, roughly EE-o

So:

• εργαλείο → er-ga-LEE-o

Also:

• βρίσκω → roughly VREE-sko
• βίδα → roughly VEE-tha in standard Greek, because δ sounds like the th in this
• δεν → roughly then with the voiced th sound of this

Yes, very naturally.

The sentence literally states inability:

• I can’t find the tool
• I can’t unscrew the screw

But in real use, it can easily express annoyance or frustration, especially in context. Greek often lets tone of voice carry that extra meaning.

So depending on delivery, it may sound like:

• I can’t find the tool, and I can’t unscrew the screw either!

Yes. It sounds like something someone might say while fixing or assembling something.

It is natural because it uses very common structures:

• δεν + verb for negation
• μπορώ να + verb for ability
• ordinary vocabulary for tools and hardware

So it is a good practical model sentence for everyday spoken Greek.
