Η συγκάτοικός μου καθαρίζει τα πλακάκια στην κουζίνα με βρεγμένο πανί και εγώ κρατάω το φαράσι.

Because in Greek, noun ending does not always tell you the gender. συγκάτοικος is a noun that can refer to either a male or a female roommate, and the article shows the gender:

• ο συγκάτοικος = the male roommate
• η συγκάτοικος = the female roommate

So in this sentence, Η συγκάτοικός μου means the speaker’s roommate is female.

This happens because μου is an enclitic word, meaning it often leans on the previous word for stress.

The noun συγκάτοικος is stressed on the antepenultimate syllable. When an enclitic like μου follows, Greek often adds an extra written accent to keep the pronunciation clear:

• alone: συγκάτοικος
• before enclitic: συγκάτοικός μου

This is a normal spelling rule in Greek.

μου means my.

Greek often places possessive words like μου, σου, του, της after the noun:

• η συγκάτοικός μου = my roommate
• το σπίτι μου = my house

This is one of the most common ways to show possession in modern Greek.

Because the subject is η συγκάτοικός μου, which is third person singular: she.

So the verb must also be third person singular:

• καθαρίζω = I clean / I am cleaning
• καθαρίζεις = you clean / you are cleaning
• καθαρίζει = he/she/it cleans / is cleaning

Here, καθαρίζει matches η συγκάτοικός μου.

It can mean both, depending on context.

In modern Greek, the present tense often covers both:

• she cleans
• she is cleaning

In this sentence, because it describes an action happening now, English would usually translate it as is cleaning.

πλακάκια is the plural of πλακάκι, which usually means tile. In everyday Greek, it often refers to floor or wall tiles.

So:

• το πλακάκι = the tile
• τα πλακάκια = the tiles

It is neuter plural, so the article is τα.

Also, the ending -άκι is often a diminutive in Greek, but in words like πλακάκι it is simply the normal everyday word for tile.

Because στην is the contracted form of σε την.

• σε = in / at / to
• την = the

Together they usually become:

• σε την → στην

So:

• στην κουζίνα = in the kitchen

This contraction is extremely common in modern Greek.

After the preposition σε (and therefore στη(ν)), Greek normally uses the accusative case, even for location.

So Greek says, literally:

• σε + accusative

Examples:

• στο σπίτι = in/at the house
• στην κουζίνα = in the kitchen
• στο σχολείο = at school

This is just how modern Greek prepositions work.

Because it means with a wet cloth, not with the wet cloth.

Greek often leaves out the article when something is:

• indefinite
• not previously identified
• mentioned as a general tool or means

So:

• με βρεγμένο πανί = with a wet cloth
• με το βρεγμένο πανί = with the wet cloth

Both are possible, but they mean slightly different things.

Because it agrees with πανί.

πανί is:

• neuter
• singular
• accusative here, because it follows με

So the adjective must match it:

• βρεγμένος = masculine
• βρεγμένη = feminine
• βρεγμένο = neuter

That is why we get βρεγμένο πανί.

Yes, κρατάω already shows that the subject is I, so εγώ is not grammatically necessary.

It is included for emphasis or contrast:

• Η συγκάτοικός μου ... και εγώ κρατάω ...

This gives the sense of:

• My roommate is cleaning ..., and I’m holding ...
• or more naturally, ... while I’m holding ...

So εγώ helps highlight the contrast between what the roommate is doing and what the speaker is doing.

Both forms exist.

• κρατάω
• κρατώ

They both mean I hold / I am holding.

In modern everyday Greek, κρατάω is very common and often sounds a bit more conversational. κρατώ is also correct and may sound a little more formal or concise, depending on context and speaker.

φαράσι is a neuter noun, so it takes the article το:

• το φαράσι = the dustpan

In this sentence it is the object of κρατάω, but for many neuter nouns the nominative and accusative singular look the same, so the form stays φαράσι.

Greek word order is more flexible than English because the endings and articles show grammatical relationships more clearly.

This sentence uses a very natural order:

• subject + verb + object + place + manner + and + subject + verb + object

But other orders are possible for emphasis, for example:

• Η συγκάτοικός μου στην κουζίνα καθαρίζει τα πλακάκια...
• Εγώ κρατάω το φαράσι και η συγκάτοικός μου καθαρίζει...

The original version sounds natural and neutral.
