Η καινούρια παπλωματοθήκη είναι πιο απαλή και ταιριάζει με το μπλε χαλί.

Because παπλωματοθήκη is a feminine noun in Greek, so it takes the feminine singular article η.

• η = feminine singular nominative
• ο = masculine singular nominative
• το = neuter singular nominative

So:

• η παπλωματοθήκη = the duvet cover

The adjective also agrees with it, which is why you get καινούρια in the feminine form too.

Because it must agree with παπλωματοθήκη, which is feminine singular nominative.

Greek adjectives change form to match the noun’s:

• gender
• number
• case

So the adjective καινούριος / καινούρια / καινούριο means new and changes like this:

• masculine: καινούριος
• feminine: καινούρια
• neuter: καινούριο

Here, since παπλωματοθήκη is feminine, you use καινούρια.

Yes. Παπλωματοθήκη is a compound noun.

It is made from:

• πάπλωμα = quilt / duvet
• θήκη = case / cover / holder

So παπλωματοθήκη literally means something like duvet-case, which is why it translates as duvet cover.

Greek often forms long compound words this way.

This means is softer.

• είναι = is
• πιο = more
• απαλή = soft, in the feminine singular form

Since the subject is η παπλωματοθήκη and that noun is feminine, the adjective απαλός must also appear in the feminine form:

• masculine: απαλός
• feminine: απαλή
• neuter: απαλό

So πιο απαλή literally means more soft, i.e. softer.

Yes. Both are possible.

Greek often forms comparatives in two ways:

1. πιο + adjective

   • πιο απαλή = softer

2. Comparative adjective ending

   • απαλότερη = softer

In everyday speech, πιο + adjective is extremely common and often feels simpler and more natural.

So these are both fine:

• είναι πιο απαλή
• είναι απαλότερη

Because its subject is singular: η καινούρια παπλωματοθήκη.

Ταιριάζει is the third person singular form of ταιριάζω:

• I match / suit = ταιριάζω
• you match / suit = ταιριάζεις
• he/she/it matches / suits = ταιριάζει

So:

• Η παπλωματοθήκη ταιριάζει... = The duvet cover matches...

It means matches with, goes with, or fits well with.

In this sentence:

• ταιριάζει με το μπλε χαλί = it matches the blue rug

The preposition με means with.

So the pattern is:

• ταιριάζω με + noun

Examples:

• Ταιριάζει με τις κουρτίνες. = It matches the curtains.
• Αυτό δεν ταιριάζει με εκείνο. = This does not go with that.

Because χαλί is a neuter noun, so it takes the neuter article το.

• το χαλί = the rug / carpet

And after με in Modern Greek, the article usually stays the same in form here:

• με το χαλί = with the rug

So:

• το μπλε χαλί = the blue rug
• με το μπλε χαλί = with the blue rug

Because μπλε is one of those color words in Greek that is usually indeclinable, meaning it does not change ending for gender, number, or case.

So you can say:

• το μπλε χαλί
• η μπλε μπλούζα
• ο μπλε τοίχος

In all of these, μπλε stays μπλε.

This is different from many other adjectives, which do change form.

Because Greek often places adjectives before the noun, especially in ordinary descriptive phrases.

So:

• η καινούρια παπλωματοθήκη = the new duvet cover

This is very natural Greek.

Greek word order is more flexible than English, so sometimes adjectives can also come after the noun, but before-the-noun placement is very common for everyday description.

Greek uses the definite article very regularly, often more regularly than English.

Here:

• Η καινούρια παπλωματοθήκη = the new duvet cover
• το μπλε χαλί = the blue rug

If the speaker is talking about specific known things, Greek normally includes the article.

That is why the sentence does not say just:

• καινούρια παπλωματοθήκη
• μπλε χαλί

Those would sound less definite and less complete in this context.

It is pronounced roughly teh-ree-AH-zee, with the stress on ά.

Greek marks the stressed syllable with an accent mark, so:

• ταιριάζει

That tells you where the main stress goes.

A rough breakdown is:

• ται-ρι-ά-ζει

The αι here sounds like e in Modern Greek.

Yes. The sentence is in the present tense.

• είναι = is
• ταιριάζει = matches / goes with

So the whole sentence describes a current state:

• the duvet cover is softer
• it matches the blue rug

Greek uses the present tense here the same way English does.

Yes. Greek, like English, can leave the second item unstated if it is understood from context.

So είναι πιο απαλή means it is softer, and the listener understands:

• softer than the old one
• softer than before
• softer than another duvet cover

The comparison target does not have to be stated if it is already clear.
