Το ταβάνι στο μπάνιο έχει λίγη υγρασία και το δωμάτιο μυρίζει άσχημα.

Yes:

• Το = the
• ταβάνι = ceiling
• στο = in the / at the
  (a contraction of σε + το)
• μπάνιο = bathroom
• έχει = has
• λίγη = a little / some
• υγρασία = moisture / dampness / humidity
• και = and
• το = the
• δωμάτιο = room
• μυρίζει = smells
• άσχημα = badly / bad

So the structure is very close to:

• The ceiling in the bathroom has some dampness, and the room smells bad.

Στο is the normal contraction of σε + το.

• σε = in, at, to
• το = the for a neuter singular noun

So:

• σε το μπάνιο → στο μπάνιο

This is extremely common in Greek.

Also, after σε, the noun is in the accusative case. With a neuter noun like μπάνιο, the accusative singular looks the same as the nominative, so you do not see a change in the noun itself.

Because all three nouns are neuter singular nouns.

In Greek, the article changes to match:

• gender
• number
• case

Here:

• το ταβάνι = the ceiling
• το μπάνιο = the bathroom
• το δωμάτιο = the room

All of them are neuter, so they take το in the forms used here.

A useful pattern: many neuter nouns end in -ι or -ο, like:

• το παιδί = the child
• το βιβλίο = the book
• το δωμάτιο = the room

Because λίγος / λίγη / λίγο has to agree with the noun it describes.

The noun υγρασία is feminine singular, so the correct form is:

• λίγη υγρασία

Compare:

• λίγος χρόνος = a little time / not much time (masculine)
• λίγη υγρασία = a little moisture (feminine)
• λίγο νερό = a little water (neuter)

So the ending changes to match the noun.

In this sentence, υγρασία means something like:

• moisture
• dampness
• humidity

In a house or apartment context, it often suggests a damp problem, not just normal air humidity.

So το ταβάνι έχει λίγη υγρασία means the ceiling has some visible dampness or moisture on it.

That is just a natural Greek way to describe a condition.

Greek often uses έχω (to have) where English might prefer a different structure. Here:

• Το ταβάνι έχει λίγη υγρασία
  literally = The ceiling has a little moisture

In natural English, you might say:

• The ceiling is a bit damp
• There is some damp on the ceiling
• The ceiling has some moisture

Greek prefers the has moisture type of expression here.

Because άσχημα is functioning as an adverb here, meaning:

• badly
• in a bad way
• more naturally in English, bad

So:

• το δωμάτιο μυρίζει άσχημα = the room smells bad

Greek often uses adverbial forms after verbs like this.

Compare:

• Τραγουδάει όμορφα = He/She sings beautifully
• Μιλάει γρήγορα = He/She speaks quickly
• Μυρίζει άσχημα = It smells bad

If you wanted an adjective, you would usually attach it to a noun, for example:

• άσχημη μυρωδιά = a bad smell

Yes. μυρίζω can work in two ways:

1. Intransitive: to smell / give off a smell

   • Το δωμάτιο μυρίζει άσχημα = The room smells bad

2. Transitive: to smell / sniff something

   • Μυρίζω το λουλούδι = I smell/sniff the flower

So the meaning depends on the structure.

In your sentence, το δωμάτιο is the thing giving off the smell, so μυρίζει means smells.

Because το δωμάτιο is the subject of a new clause, and in Greek definite nouns normally keep their article.

So the sentence has two coordinated parts:

• Το ταβάνι στο μπάνιο έχει λίγη υγρασία
• και το δωμάτιο μυρίζει άσχημα

Greek does not usually drop the definite article the way English sometimes can in special styles. Here, και δωμάτιο would sound incomplete or unnatural.

Greek word order is fairly flexible, though the original sentence is a very natural neutral order.

Original:

• Το ταβάνι στο μπάνιο έχει λίγη υγρασία και το δωμάτιο μυρίζει άσχημα.

You could also say:

• Στο μπάνιο το ταβάνι έχει λίγη υγρασία...

That puts more focus on in the bathroom.

Greek uses articles and case more than English does, so it can move pieces around more easily. But the version you have is a standard, neutral way to say it.

It can mean both, depending on context.

• το μπάνιο = the bathroom
• το μπάνιο can also mean the bath or bathing

In this sentence, because of στο μπάνιο after ceiling, it clearly means:

• in the bathroom

Context tells you which meaning is intended.

Yes.

• έχει = it has
• μυρίζει = it smells

Both are present tense, third person singular.

The subjects are both singular neuter nouns:

• το ταβάνι → έχει
• το δωμάτιο → μυρίζει

Greek verbs do not change form based on gender, only on person and number, so a masculine, feminine, or neuter singular subject would all use the same third person singular verb form.

A rough pronunciation guide is:

to ta-VA-ni sto BAN-yo E-hi LI-yi i-gra-SI-a ke to tho-MA-tio mi-RI-zi A-shee-ma

A few useful pronunciation notes:

• μπ in μπάνιο is pronounced like b
• νι in μπάνιο sounds like ny in canyon
• γ before η / ι in λίγη is a soft sound, roughly like y with friction
• δ in δωμάτιο is like th in this
• χ in άσχημα is a soft sound, like German ich or a very soft h-like sound made further back

The written stress marks show you where the stress falls:

• ταβάνι
• μπάνιο
• υγρασία
• δωμάτιο
• μυρίζει
• άσχημα
