Αν δεν προσέχω, σπάζω εύκολα ποτήρια όταν βιάζομαι στην κουζίνα.

Because this sentence describes a general/habitual situation, not one specific event.

• Αν δεν προσέχω = If I’m not careful
• σπάζω εύκολα ποτήρια = I easily break glasses
• όταν βιάζομαι = when/whenever I’m in a hurry

So the idea is: This is what usually happens.

If Greek wanted to talk about one specific future case, it would normally use a different pattern, for example:

• Αν δεν προσέξω, θα σπάσω ποτήρια.
• If I’m not careful, I’ll break glasses.

So the present tense here is about repeated behavior.

This is a very common learner question, because both can translate as if I’m not careful.

The difference is mainly about habitual vs specific meaning:

• Αν δεν προσέχω = if I’m not careful / when I’m not careful in a general, repeated sense
• Αν δεν προσέξω = if I’m not careful in a particular future situation

So in your sentence:

• Αν δεν προσέχω, σπάζω εύκολα ποτήρια... = Whenever I’m not careful, I easily break glasses...

But:

• Αν δεν προσέξω, θα σπάσω ένα ποτήρι. = If I’m not careful, I’ll break a glass.

So προσέχω fits the sentence because the whole statement is about a regular pattern.

Because the sentence is not talking about the future in the usual sense. It is describing a habit or a general truth.

• σπάζω εύκολα ποτήρια = I easily break glasses
• not I will break glasses

Greek often uses the present tense without θα for things that happen regularly.

Compare:

• Αν δεν προσέχω, σπάζω εύκολα ποτήρια. = If I’m not careful, I easily break glasses.

with

• Αν δεν προσέξω, θα σπάσω ποτήρια. = If I’m not careful, I’ll break glasses.

So the absence of θα helps show that this is habitual, not a one-time future result.

In this sentence, όταν can be understood as when or whenever, but in natural English whenever brings out the repeated meaning more clearly.

• όταν βιάζομαι literally = when I’m in a hurry
• in context = whenever I’m in a hurry

Because the whole sentence is habitual, όταν does not mean one specific time. It means every time that happens.

So the sentence has the sense:

• If I’m not careful, I easily break glasses whenever I’m in a hurry in the kitchen.

βιάζομαι means I hurry / I am in a hurry / I rush.

It looks like a passive-form verb because it ends in -ομαι, but here it is not passive in meaning. This is normal in Greek: some verbs use these endings but have an active meaning.

So:

• βιάζομαι = I’m in a hurry / I rush
• όταν βιάζομαι = when I’m in a hurry

A useful thing to remember is that you should learn βιάζομαι as a whole vocabulary item, not try to force it into an English-style active/passive pattern.

Because ποτήρια here means glasses in a general, indefinite sense.

• σπάζω εύκολα ποτήρια = I easily break glasses
• not I easily break the glasses

Greek often leaves out the article when speaking about indefinite plural things in a general way.

Compare:

• σπάζω εύκολα ποτήρια = I easily break glasses
• σπάζω εύκολα τα ποτήρια = I easily break the glasses

The second version would sound like we are talking about specific glasses already known in the conversation.

Here it means drinking glasses.

The singular is:

• το ποτήρι = glass

The plural is:

• τα ποτήρια = glasses

In this kitchen context, it clearly means drinking glasses, not spectacles/eyeglasses.

εύκολα means easily. It is an adverb, and it modifies the verb σπάζω.

So:

• σπάζω εύκολα ποτήρια = I easily break glasses

Greek word order is more flexible than English word order, so adverbs like εύκολα can often move around for emphasis or style.

For example, these are all possible with slightly different rhythm/emphasis:

• σπάζω εύκολα ποτήρια
• εύκολα σπάζω ποτήρια
• σπάζω ποτήρια εύκολα

The given order is very natural.

στην is the contracted form of:

• σε + την = στην

Here it means in the or to the, depending on context.

So:

• στην κουζίνα = in the kitchen

In this sentence, it clearly means location:

• όταν βιάζομαι στην κουζίνα = when I’m in a hurry in the kitchen

This contraction is extremely common in Greek:

• στον = σε τον
• στη(ν) = σε τη(ν)
• στο = σε το

The sentence is arranged very naturally in Greek:

• Αν δεν προσέχω, the condition: If I’m not careful
• σπάζω εύκολα ποτήρια the main result: I easily break glasses
• όταν βιάζομαι στην κουζίνα the time/circumstance: when I’m in a hurry in the kitchen

Greek often puts the condition first, just as English does. After that comes the main statement, and then an extra phrase explaining when it happens.

A more literal structure would be:

• If I’m not careful, I easily break glasses when I’m hurrying in the kitchen.

So the word order is not strange; it is a normal Greek way to build the sentence step by step.

Yes. In Modern Greek, both σπάζω and σπάω are used for I break.

• σπάζω is very common and standard
• σπάω is also common, especially in everyday speech

So you may hear:

• σπάζω ποτήρια
• σπάω ποτήρια

Both are natural. In your sentence, σπάζω is completely normal.
