Το μαλλί μου είναι ακόμα βρεγμένο από το ντους.

Yes. μαλλί can mean both hair and wool in Greek.

Context tells you which one is meant:

• το μαλλί μου
  • βρεγμένο από το ντους clearly means my hair
• in other contexts, μαλλί can mean wool as a material

So this is one of those words whose meaning depends strongly on the situation.

Greek can talk about hair in two ways:

• το μαλλί μου = my hair, seen as one mass / overall hair
• τα μαλλιά μου = my hair, seen as plural hairs

Both are possible. For a person's hair, many learners will hear τα μαλλιά μου very often, and Τα μαλλιά μου είναι ακόμα βρεγμένα is a very natural alternative.

So the sentence is not wrong; it is just using the singular collective idea of hair.

Because Greek normally keeps the definite article with possessed nouns.

So Greek says:

• το μαλλί μου = literally the hair my
• το σπίτι μου = my house
• η αδερφή μου = my sister

This is completely normal Greek structure. The article does not disappear just because you have μου.

Because μου here is a weak possessive form, and in Greek these usually come after the noun.

Examples:

• το βιβλίο μου = my book
• η τσάντα μου = my bag
• το μαλλί μου = my hair

So although English puts my before the noun, Greek usually puts μου after it.

Because adjectives in Greek must agree with the noun in gender and number.

Here:

• μαλλί is neuter singular
• so the adjective must also be neuter singular
• therefore: βρεγμένο

Compare:

• το μαλλί μου είναι βρεγμένο
• τα μαλλιά μου είναι βρεγμένα

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

Here ακόμα means still.

So it adds the idea that the hair continues to be wet.

In other contexts, ακόμα can also mean things like yet or even, but in this sentence still is the natural meaning.

You may also see ακόμη, which is usually just a variant spelling/style of the same word in Modern Greek.

Yes, από often means from, and that is basically the idea here too.

από το ντους means the hair is wet from the shower, meaning because of the shower.

So it expresses source/cause:

• the shower is what caused the hair to be wet

In natural English, we might say:

• from the shower
• after the shower

But in Greek, από is very normal here.

Yes, you could, but the nuance is a little different.

• από το ντους = wet from the shower, emphasizing the cause/source
• μετά το ντους = wet after the shower, emphasizing the time

Both can work, but από το ντους fits especially well when you want the idea the shower is why it’s wet.

ντους is a loanword, and in Modern Greek it is usually treated as an indeclinable neuter noun.

That means the article changes as needed, but ντους itself usually stays the same:

• το ντους
• από το ντους
• στο ντους

So learners often notice that the noun itself does not show the usual case endings.

In a normal present-tense sentence like this, είναι is needed.

So:

• Το μαλλί μου είναι βρεγμένο = correct

Greek does not normally drop the present-tense to be in this kind of standard statement.

You would need to change both the noun and the adjective so they agree:

• Το μαλλί μου είναι ακόμα βρεγμένο
• Τα μαλλιά μου είναι ακόμα βρεγμένα

The main change is:

• μαλλί → μαλλιά
• βρεγμένο → βρεγμένα

So once you switch to plural hair, the adjective must also become plural.

A rough pronunciation guide is:

to ma-LEE moo EE-ne A-ko-ma vregh-ME-no a-PO to doos

A few useful points:

• μαλλί is stressed on the last syllable: μα-λλί
• βρεγμένο is stressed on -μέ-
• ντους is pronounced roughly like doos
• the double λλ in μαλλί does not mean you hold the sound extra long in the English way; it is just part of the spelling

So the rhythm is something like:

Το μαλλί μου | είναι ακόμα | βρεγμένο | από το ντους
