Αν το μπλέντερ κάνει πολύ θόρυβο το πρωί, η συγκάτοικός μου ξυπνάει αμέσως.

After αν (if), Greek normally uses the plain finite verb form. You do not put να after αν, and standard Greek also avoids θα inside the if-clause.

So:

• αν κάνει = correct
• αν να κάνει = not correct
• αν θα κάνει = normally not used in standard Greek for this kind of sentence

Here κάνει is present tense because the sentence describes a regular situation.

It describes a general repeated situation: whenever / if the blender makes a lot of noise in the morning, my roommate wakes up immediately.

This is similar to the English zero conditional:

• If X happens, Y happens.

Because of that, both verbs are in the present:

• κάνει
• ξυπνάει

If you wanted to talk about one future occasion, Greek would more naturally use a future form in the main clause, for example:

• Αν το μπλέντερ κάνει πολύ θόρυβο το πρωί, η συγκάτοικός μου θα ξυπνήσει αμέσως.

μπλέντερ is a loanword, and many loanwords in Modern Greek are treated as neuter, especially objects and machine names.

So Greek uses:

• το μπλέντερ

Also, words like this are often indeclinable, meaning the noun itself does not change form much; the article shows the grammar:

• το μπλέντερ
• του μπλέντερ
• τα μπλέντερ

That is very normal for borrowed words.

Because κάνω θόρυβο is a very common Greek expression meaning make noise or be noisy.

So:

• Το μπλέντερ κάνει θόρυβο = The blender makes noise / is noisy

This is more idiomatic than trying to translate English word-for-word. Greek often prefers a verb + noun expression where English might use an adjective.

Also, θόρυβο is in the accusative because it is the direct object of κάνει.

Because πολύς changes form depending on gender, number, and case.

Its basic singular forms are:

• masculine: πολύς
• feminine: πολλή
• neuter: πολύ

But here it goes with θόρυβο, which is masculine accusative singular, so the correct form is:

• πολύ θόρυβο

Compare:

• πολύς θόρυβος = a lot of noise / much noise (nominative)
• κάνει πολύ θόρυβο = makes a lot of noise (accusative)

So πολύ here is the correct form for this noun phrase.

In Greek, time expressions often use the definite article:

• το πρωί = in the morning
• το βράδυ = in the evening / at night
• το καλοκαίρι = in the summer

So το πρωί is the normal Greek way to say in the morning.

Depending on context, το πρωί can sometimes mean this morning, but in this sentence, because the whole sentence is habitual, it means in the morning in a general sense.

Because in Greek, the ending -ος is not always masculine.

Some nouns in -ος can be:

• masculine
• feminine
• common gender depending on the article

Here the article tells you the gender:

• η συγκάτοικος = female roommate
• ο συγκάτοικος = male roommate

So the ending alone does not tell you the whole story; the article is very important.

Because μου is an enclitic word, and Greek spelling adds an extra written accent in certain cases when an enclitic follows a word stressed on the antepenultimate syllable.

Base form:

• η συγκάτοικος

Before μου:

• η συγκάτοικός μου

This extra accent helps preserve the stress pattern clearly in writing. You see the same thing in many common phrases, for example:

• ο άνθρωπός μου

So this is a normal spelling rule, not a different word.

Because Greek usually expresses simple possession with the pattern:

noun + weak possessive pronoun

So:

• η συγκάτοικός μου = my roommate
• το σπίτι μου = my house
• η αδερφή μου = my sister

This is the standard everyday pattern in Modern Greek. English puts my before the noun, but Greek usually puts μου after it.

Both are correct.

The verb can appear as:

• ξυπνάει
• ξυπνά

Both mean wakes up here. This comes from the verb ξυπνάω / ξυπνώ.

So you may see:

• η συγκάτοικός μου ξυπνάει αμέσως
• η συγκάτοικός μου ξυπνά αμέσως

Both are acceptable Modern Greek.

The word order can change. Greek is more flexible than English.

For example, you could also say:

• Η συγκάτοικός μου ξυπνάει αμέσως αν το μπλέντερ κάνει πολύ θόρυβο το πρωί.

That means the same thing. The original version puts the condition first, which is very natural and often sounds slightly more organized or emphatic.

Also, the comma is normal when the αν-clause comes first:

• Αν ..., ...

Because Greek usually does not need a subject pronoun if the subject is already clear.

Here the subject is already stated:

• η συγκάτοικός μου

So there is no need to add αυτή.

Greek verb endings also carry person and number information, so subject pronouns are often omitted unless you want extra emphasis or contrast.
