Η αδερφή μου άλλαξε μπλούζα, γιατί η πρώτη ήταν ακόμα μουσκεμένη και δεν ένιωθε καθόλου άνετα.

In Greek, possessive phrases usually keep the definite article:

• η αδερφή μου = my sister
• το σπίτι μου = my house
• οι φίλοι μου = my friends

So Greek normally says the sister of me, not just sister my.

Without the article, αδερφή μου can still appear, but it often sounds more like direct address or a special stylistic use, for example Αδερφή μου! = My sister! / Sister!

In a normal statement, Η αδερφή μου is the expected form.

Άλλαξε is the aorist form of αλλάζω, meaning changed.

Here it means:

• Η αδερφή μου άλλαξε μπλούζα = My sister changed her top/shirt

The aorist is used because this is seen as a completed action: she changed clothes.

A few useful related forms:

• αλλάζω = I change / I am changing
• άλλαξα = I changed
• άλλαξε = he/she/it changed

So άλλαξε is a simple past action.

Greek often leaves out the article with clothing after verbs like change, when the meaning is general:

• άλλαξε μπλούζα = she changed top/shirt
• άλλαξε παπούτσια = she changed shoes
• άλλαξε ρούχα = she changed clothes

This sounds natural when the focus is on the act of changing what she was wearing.

If you say άλλαξε τη μπλούζα, it sounds more specific:

• she changed the blouse
• she replaced that particular blouse with another one

So:

• άλλαξε μπλούζα = changed clothes / changed her top
• άλλαξε τη μπλούζα = changed that specific top

Μπλούζα is a broad everyday word. Depending on context, it can mean:

• top
• shirt
• blouse
• sometimes T-shirt

In this sentence, top or shirt is probably the safest translation, because the exact type of garment is not the main point.

Greek clothing words do not always match English clothing words one-to-one, so context matters.

Η πρώτη literally means the first (one).

What is understood is μπλούζα:

• η πρώτη [μπλούζα] = the first top / the first one

Greek often leaves out a noun when it is obvious from context. English does the same:

• I like the red shirt, not the blue one
• Greek can similarly just use the adjective with the article.

So η πρώτη means the first one, and it is feminine because it refers to μπλούζα, which is feminine.

Because it agrees with μπλούζα, which is feminine.

Greek adjectives must agree with the noun in:

• gender
• number
• case

Here:

• μπλούζα is feminine singular
• so the adjective must also be feminine singular: πρώτη

Compare:

• η πρώτη μπλούζα = the first top
• το πρώτο βιβλίο = the first book
• ο πρώτος άνθρωπος = the first person/man

Here ακόμα means still:

• ήταν ακόμα μουσκεμένη = it was still soaked

This is a very common use of ακόμα.

Be careful, because ακόμα can also mean even in other contexts:

• Ακόμα και αυτός το ξέρει = Even he knows it

So the meaning depends on the sentence. Here it clearly means still.

Μουσκεμένη means soaked, drenched, or very wet.

It is an adjective, and it agrees with the noun it describes:

• η μπλούζα is feminine singular
• so the adjective is feminine singular too: μουσκεμένη

Compare:

• το πουκάμισο ήταν μουσκεμένο = the shirt was soaked
• η μπλούζα ήταν μουσκεμένη = the top was soaked
• τα ρούχα ήταν μουσκεμένα = the clothes were soaked

So the ending changes because Greek adjectives agree with the noun.

Ένιωθε is the imperfect of νιώθω, while ένιωσε is the aorist.

In this sentence, δεν ένιωθε καθόλου άνετα describes an ongoing state or condition in the past:

• she wasn’t feeling comfortable
• she didn’t feel comfortable

The imperfect is natural for background description or a continuing feeling.

Compare:

• δεν ένιωθε άνετα = she wasn’t feeling comfortable / she did not feel comfortable
• δεν ένιωσε άνετα = she did not feel comfortable at a specific moment

So the sentence uses ένιωθε because it fits the descriptive background: the top was wet, and as a result she was uncomfortable.

With νιώθω, Greek usually says νιώθω άνετα, using the adverb άνετα.

So:

• νιώθω άνετα = I feel comfortable
• δεν ένιωθε άνετα = she didn’t feel comfortable

This is one of those expressions where Greek prefers the adverb.

If you used άνετη, that would be an adjective describing a feminine person or thing, but after νιώθω, the adverb άνετα is the normal idiomatic choice.

Καθόλου means at all in negative sentences.

So:

• δεν ένιωθε άνετα = she didn’t feel comfortable
• δεν ένιωθε καθόλου άνετα = she didn’t feel comfortable at all

It strengthens the negation.

You will see καθόλου very often with δεν:

• δεν μου αρέσει καθόλου = I don’t like it at all
• δεν κουράστηκα καθόλου = I didn’t get tired at all

Greek often omits subject pronouns because the verb ending already shows the person.

In this sentence:

• άλλαξε = she changed
• ένιωθε = she felt / was feeling

So Greek does not need to repeat αυτή (she).

Also, context makes it clear that the subject continues to be my sister:

• Η αδερφή μου άλλαξε μπλούζα
• because the first one was still soaked
• and (she) didn’t feel comfortable at all

This is very normal Greek style.

Γιατί here means because.

It introduces the reason:

• Η αδερφή μου άλλαξε μπλούζα = My sister changed her top
• γιατί... = because...

So the second part explains why she changed it.

Be aware that γιατί can also mean why in questions:

• Γιατί έφυγες; = Why did you leave?

So the same word can mean:

• because
• why

The function depends on the sentence.

The given word order is natural, but Greek word order is more flexible than English.

Original:

• Η αδερφή μου άλλαξε μπλούζα, γιατί η πρώτη ήταν ακόμα μουσκεμένη και δεν ένιωθε καθόλου άνετα.

This is a straightforward, neutral way to say it.

You could move things around for emphasis, but not always in the same way English does. For example:

• Γιατί η πρώτη ήταν ακόμα μουσκεμένη, η αδερφή μου άλλαξε μπλούζα.

This is possible, but it sounds more marked because the reason comes first.

So yes, word order can vary, but the original is the most natural neutral version.

Yes, αδερφή is very common in everyday Modern Greek.

You may also see:

• αδελφή

Both refer to sister, but:

• αδερφή is the usual everyday form in spoken and informal written Greek
• αδελφή can sound more formal, conservative, or learned

The same happens with:

• αδερφός / αδελφός = brother

So in this sentence, αδερφή is completely natural.
