Το κίτρινο φούτερ είναι πιο χαρούμενο από το γκρι, αλλά το μωβ δεν ταιριάζει με όλα.

Φούτερ is a loanword in Modern Greek, and it is normally treated as a neuter noun. That is why it takes the neuter article το.

Because the noun is neuter singular, the adjective describing it must also be neuter singular:

• το κίτρινο φούτερ

So the gender is coming from φούτερ, not from the color itself.

The adjective κίτρινος means yellow and changes form to match the noun it describes.

Its basic pattern is:

• κίτρινος masculine
• κίτρινη feminine
• κίτρινο neuter

Since φούτερ is neuter singular, the correct form is κίτρινο.

Many color words in Greek, especially borrowed ones like γκρι and μωβ, are often indeclinable. That means they stay the same instead of changing for gender and number.

For example, you can hear:

• το γκρι φούτερ
• η γκρι μπλούζα
• τα γκρι παπούτσια

and similarly:

• το μωβ φόρεμα
• η μωβ τσάντα

So unlike κίτρινος / κίτρινη / κίτρινο, these color words often keep one fixed form.

This is the standard Greek way to make a comparison:

• πιο = more
• adjective
• από = than

So the pattern is:

πιο + adjective + από + noun/pronoun

Examples:

• πιο μεγάλο από ... = bigger than ...
• πιο όμορφο από ... = more beautiful than ...
• πιο χαρούμενο από ... = happier / more cheerful than ...

This is a very common and useful comparative structure in Greek.

Because χαρούμενο is agreeing with the subject, which is το κίτρινο φούτερ.

Even after είναι, Greek adjectives still agree with the noun they describe:

• το φούτερ είναι χαρούμενο
• η μπλούζα είναι χαρούμενη
• ο τόνος είναι χαρούμενος

So here the adjective must be neuter singular, which gives χαρούμενο.

Because το γκρι means the gray one. The noun φούτερ is being left out because it is already understood from the context.

So:

• από το γκρι really means από το γκρι φούτερ

This is very common in Greek. When the noun is obvious, Greek often uses:

• article + adjective/color

to mean:

• the ... one

So το γκρι = the gray one.

In Modern Greek, από takes the accusative.

In this sentence, you see:

• από το γκρι

The article το looks the same in nominative and accusative because it is neuter singular, so there is no visible change here.

A clearer example with a masculine noun/article would be:

• από τον φίλο
• από τον μπλε σάκο

So yes, από is followed by the accusative, even if this sentence does not make that very obvious.

For the same reason as το γκρι above: Greek often omits a repeated noun when it is clear from context.

So:

• το μωβ = the purple one
• here, more specifically, the purple hoodie/sweatshirt

This kind of omission is very natural in Greek and sounds much less repetitive than repeating φούτερ again.

The verb ταιριάζω often means match, go with, or fit well with. When you say what something matches, Greek normally uses με:

• ταιριάζει με το παντελόνι
• ταιριάζει με αυτά τα παπούτσια
• δεν ταιριάζει με όλα

So με is the normal preposition here for the thing it matches with.

Here όλα means everything or more literally all things.

It is the neuter plural form of όλος used on its own, without a noun:

• όλα = everything / all things

So:

• με όλα = with everything

A very similar alternative you may also hear is:

• με τα πάντα

Both are natural, but με όλα is perfectly standard.

Not completely. Greek word order is more flexible than English word order. The sentence as written is a natural, neutral way to say it:

• Το κίτρινο φούτερ είναι πιο χαρούμενο από το γκρι, αλλά το μωβ δεν ταιριάζει με όλα.

You can move things around for emphasis, but for a learner this order is a good model to follow:

• subject
• verb
• comparison
• αλλά
• subject
• verb
• prepositional phrase

So the order here is not the only possible one, but it is very standard and natural.
