Το βαμβακερό πουκάμισο είναι πιο άνετο για το γραφείο, αλλά το δερμάτινο μπουφάν έχει ωραίο στυλ.

Because both nouns are neuter singular.

• το πουκάμισο = the shirt
• το μπουφάν = the jacket

In Greek, the definite article changes according to gender, number, and case. Here both nouns are the subject (or part of the subject) and are neuter singular nominative, so the article is το.

They are adjectives and they must agree with the nouns they describe.

• βαμβακερό matches πουκάμισο
• δερμάτινο matches μπουφάν

Since both nouns are neuter singular, the adjectives are also in the neuter singular form.

So:

• βαμβακερός / βαμβακερή / βαμβακερό
• δερμάτινος / δερμάτινη / δερμάτινο

Greek adjectives change form much more than English adjectives do.

Yes, here βαμβακερό means cotton in the sense of made of cotton.

It comes from βαμβάκι = cotton.

So:

• βαμβακερό πουκάμισο = cotton shirt
• literally, something like cotton-made shirt

This is very common in Greek: a material noun can produce an adjective meaning made of that material.

Δερμάτινο means leather or made of leather.

It comes from δέρμα = skin / leather.

So:

• δερμάτινο μπουφάν = leather jacket

Just like βαμβακερό, it is an adjective describing the material.

In Modern Greek, the very common way to form the comparative is:

πιο + adjective

So:

• άνετο = comfortable
• πιο άνετο = more comfortable

This is the easiest and most common pattern in everyday Greek.

There are also some older or more formal comparative forms in Greek, but πιο + adjective is the normal one learners should get used to first.

Because it refers back to το βαμβακερό πουκάμισο, which is neuter singular.

Greek adjectives agree with the noun they describe, even after the verb είναι.

So:

• το πουκάμισο είναι άνετο = the shirt is comfortable
• το πουκάμισο είναι πιο άνετο = the shirt is more comfortable

If the noun were feminine or masculine, the adjective would change too.

Because this sentence is not making a full direct comparison like more comfortable than the jacket.

It says:

Το βαμβακερό πουκάμισο είναι πιο άνετο για το γραφείο = The cotton shirt is more comfortable for the office

This means something like better/more comfortable for office use. The comparison is understood from the context, especially because the sentence then contrasts it with the leather jacket.

If you wanted to say more comfortable than the leather jacket, you would say:

Το βαμβακερό πουκάμισο είναι πιο άνετο από το δερμάτινο μπουφάν.

Here από means than in comparisons.

Literally, για το γραφείο means for the office.

• για = for
• το γραφείο = the office

Greek often uses the article in places where English may sound more flexible. In English, we might say for the office or just think of office wear, but in Greek για το γραφείο is very natural.

It means:

• suitable for the office
• appropriate to wear at the office

Αλλά means but.

It connects the two contrasting ideas:

• the cotton shirt is more comfortable for the office
• but the leather jacket has nice style

So αλλά introduces a contrast, just like but in English.

Because έχει ωραίο στυλ is a very natural Greek way to express the idea that something looks stylish or has good style.

Literally it means:

• έχει = has
• ωραίο = nice
• στυλ = style

So the phrase means it has nice style, but idiomatically in English that often becomes:

• it looks stylish
• it has a nice style
• it’s stylish

Greek often uses έχω in expressions where English might prefer an adjective.

Because it is being used as an indefinite noun phrase:

ωραίο στυλ = nice style

Greek does not have a separate word for a/an, so an indefinite noun often appears without an article.

Compare:

• έχει στυλ = it has style
• έχει ωραίο στυλ = it has nice style / a nice style
• έχει το στυλ που μου αρέσει = it has the style that I like

So the lack of article here does not mean something is missing; it is normal Greek.

Because μπουφάν is a loanword, and many loanwords in Greek are neuter.

Greek gender is not determined only by spelling. While many neuter nouns do end in -ο, some common borrowed words do not, for example:

• το μπουφάν = the jacket
• το στυλ = the style

These words are often treated as indeclinable or only minimally declined, and the article tells you the gender very clearly.

Yes, στυλ is normally neuter.

You can see that in phrases like:

• το στυλ = the style
• ωραίο στυλ = nice style

The adjective ωραίο is in the neuter singular form, which matches στυλ.

In Greek, adjectives often come before the noun, especially in straightforward descriptive phrases like these:

• το βαμβακερό πουκάμισο
• το δερμάτινο μπουφάν

That is the most natural order here.

Greek can sometimes place adjectives after the noun, but that usually sounds more marked, more specific, or depends on the adjective and context. For a learner, the safest default is:

article + adjective + noun

when you are simply describing something.

It has two main clauses joined by αλλά:

1. Το βαμβακερό πουκάμισο είναι πιο άνετο για το γραφείο

   • subject: Το βαμβακερό πουκάμισο
   • verb: είναι
   • complement: πιο άνετο
   • extra phrase: για το γραφείο

2. το δερμάτινο μπουφάν έχει ωραίο στυλ

   • subject: το δερμάτινο μπουφάν
   • verb: έχει
   • object: ωραίο στυλ

So the overall pattern is:

[Thing 1] is ... , but [Thing 2] has ...

You would need to change the articles, nouns, adjectives, and parts that agree with them.

For example:

Τα βαμβακερά πουκάμισα είναι πιο άνετα για το γραφείο, αλλά τα δερμάτινα μπουφάν έχουν ωραίο στυλ.

Notice the changes:

• το → τα
• βαμβακερό → βαμβακερά
• πουκάμισο → πουκάμισα
• είναι πιο άνετο → είναι πιο άνετα
• το δερμάτινο μπουφάν → τα δερμάτινα μπουφάν
• έχει → έχουν

This is a good example of how much agreement matters in Greek.

A few useful ones are:

• βαμβακερό
• πουκάμισο
• είναι
• άνετο
• γραφείο
• δερμάτινο
• μπουφάν
• ωραίο
• στυλ

Stress is important in Greek, and it is written, so learners should make a habit of noticing it every time.

A few especially useful pronunciation notes:

• είναι is pronounced roughly like EE-ne
• ωραίο is often pronounced in connected speech close to o-RE-o
• μπ at the start of μπουφάν sounds like b

Yes. That would mean:

The cotton shirt is comfortable for the office.

Adding πιο changes it to:

The cotton shirt is more comfortable for the office.

So:

• άνετο = comfortable
• πιο άνετο = more comfortable

Both are grammatically correct; they just express different meanings.

Yes, it sounds natural and useful for everyday description and comparison.

It combines several very common Greek patterns:

• article + adjective + noun
• πιο + adjective
• για + article + noun
• αλλά for contrast
• έχει + noun phrase to describe style or qualities

So it is a very good sentence for practicing practical Greek grammar and vocabulary.
