Η επιβάτισσα μπροστά μου ρώτησε πού είναι η τουαλέτα.

Επιβάτισσα means female passenger. It is the feminine form of επιβάτης (passenger, masculine or sometimes mixed/default in some contexts).

So in this sentence, the speaker is specifically referring to a woman: Η επιβάτισσα = the female passenger.

Η is the feminine singular definite article, meaning the.

• Η επιβάτισσα = the female passenger
• η τουαλέτα = the toilet

Greek uses articles very regularly, often more consistently than English. Here both nouns are feminine singular, so both take η.

Literally, μπροστά μου means in front of me.

• μπροστά = in front
• μου = of me / my

So the structure is very natural Greek:

• μπροστά μου = in front of me
• δίπλα μου = next to me
• πίσω μου = behind me

Because in Greek, words like μπροστά, πίσω, δίπλα, κοντά are commonly followed by a weak pronoun such as μου, σου, του, etc.

So Greek says:

• μπροστά μου = in front of me
• πίσω σου = behind you

Putting μου first would sound wrong here. The normal pattern is location word + pronoun.

Because μου is the normal unstressed form used in expressions like this.

• μπροστά μου = in front of me
• δίπλα μου = next to me

You could use εμένα for emphasis in some contexts, but not as the normal everyday form here. In this sentence, μου is exactly what Greek naturally uses.

Ρώτησε is the aorist form of ρωτάω / ρωτώ (to ask).

Here it means asked as a single completed action in the past:

• ρωτάει = he/she asks / is asking
• ρώτησε = he/she asked

So Η επιβάτισσα μπροστά μου ρώτησε... means The female passenger in front of me asked...

Because Greek does not have to shift the tense backward the way English often does.

English often says:

• She asked where the toilet was

But Greek can naturally say:

• ρώτησε πού είναι η τουαλέτα
• literally: asked where the toilet is

This is normal in Greek. The question being reported is still about the toilet’s current location, so present είναι works perfectly.

Because Greek often keeps the same word order in both direct and indirect questions.

Direct question:

• Πού είναι η τουαλέτα;
• Where is the toilet?

Indirect question:

• ρώτησε πού είναι η τουαλέτα
• she asked where the toilet is/was

Unlike English, Greek does not need a special word order like where the toilet was. It simply keeps πού είναι η τουαλέτα.

Here πού means where, and it is written with an accent.

That helps distinguish it from που, which often means that / which / who in relative clauses.

Compare:

• πού είναι η τουαλέτα; = where is the toilet?
• το βιβλίο που θέλω = the book that I want

So the accent helps show that this is the question word where.

Yes. Πού βρίσκεται η τουαλέτα; is also correct and means Where is the toilet located?

But πού είναι η τουαλέτα is more everyday and conversational.
βρίσκεται sounds a bit more formal or more explicitly about location.

So in normal speech, πού είναι η τουαλέτα is very natural.

A rough pronunciation guide is:

ee epi-VA-ti-sa bro-STAH moo RO-ti-se poo EE-ne ee too-a-LE-ta

A few helpful points:

• η / οι / ει / ι / υ all sound like ee
• μπ at the start of a word is usually pronounced like b
• ου sounds like oo
• αι sounds like e in met

So:

• Η = ee
• μπροστά = bro-STAH
• μου = moo
• πού = poo
• είναι = EE-ne

Επιβάτισσα is correct and clear, especially if you want to specify that the passenger is a woman.

But in everyday Greek, people often use επιβάτης more generally, especially when gender is not important. Still, επιβάτισσα is a perfectly normal word and fits this sentence well because the person is clearly female.

In this sentence it clearly refers to physical position: the passenger in front of me.

More generally, μπροστά can also be used in time or figurative expressions, but here it is purely spatial.

So:

• Η επιβάτισσα μπροστά μου = the female passenger sitting/standing in front of me

That is a very natural way to describe someone’s position.
