Η αμφιβολία μου φεύγει όταν μιλάω με τη δασκάλα μου.

Greek uses the definite article much more often than English. So η αμφιβολία μου literally looks like the doubt my, but it simply means my doubt.

This is very normal in Greek:

• το βιβλίο μου = my book
• η φίλη μου = my friend
• η αμφιβολία μου = my doubt

So the article is not unusual here; it is the standard Greek pattern.

In Greek, possessive words like μου (my), σου (your), του/της (his/her) usually come after the noun:

• η αμφιβολία μου = my doubt
• η δασκάλα μου = my teacher

This is one of the most common Greek word orders for possession. English puts my before the noun, but Greek often puts μου after it.

Αμφιβολία means doubt, uncertainty, or hesitation depending on context.

It is a feminine noun:

• η αμφιβολία = the doubt
• της αμφιβολίας = of the doubt

In this sentence, it refers to a feeling of uncertainty.

Yes, φεύγω literally means to leave or to go away. But Greek often uses it figuratively, just like English can say:

• my fear goes away
• the pain leaves
• my doubt disappears

So Η αμφιβολία μου φεύγει is a natural way to say that the doubt goes away or disappears.

The present tense here expresses something general, habitual, or repeated:

• Η αμφιβολία μου φεύγει όταν μιλάω με τη δασκάλα μου.

This means something like:

• My doubt goes away whenever I talk to my teacher.

It is not necessarily happening only right now; it can describe a repeated pattern.

Όταν means when. It is used for something that happens whenever a certain situation occurs.

• όταν μιλάω με τη δασκάλα μου = when/whenever I talk to my teacher

Αν means if, so it would introduce a condition instead:

• Αν μιλάω... = If I talk...

Here the speaker is not presenting a condition as uncertain; they are describing what happens whenever they speak with the teacher. So όταν is the right choice.

For the same reason: the sentence describes a repeated or usual situation.

• φεύγει = goes away
• μιλάω = I talk / I am talking

With όταν + present, Greek can express whenever something happens:

• Όταν μιλάω με τη δασκάλα μου, η αμφιβολία μου φεύγει.
• Whenever I talk to my teacher, my doubt goes away.

So the present tense is very natural here.

Yes. Both are correct.

• μιλάω
• μιλώ

They both mean I speak / I talk. In everyday modern Greek, μιλάω is very common, and μιλώ is also standard. Many verbs in Greek have this kind of double present form.

Examples:

• μιλάω ελληνικά = I speak Greek
• μιλώ ελληνικά = same meaning

The preposition με means with and is followed by the accusative case.

So:

• η δασκάλα = nominative, the teacher
• τη δασκάλα = accusative, the teacher after with

That is why we get:

• με τη δασκάλα μου = with my teacher

This is a very common Greek pattern:

• με τον φίλο μου = with my friend
• με τη μητέρα μου = with my mother

Both exist, but τη is the shortened form of την before a consonant in ordinary speech and writing.

So:

• τη δασκάλα
• την δασκάλα

Both are correct, but τη δασκάλα is very common and natural in modern Greek.

Before a vowel or certain consonant combinations, you are more likely to keep the full form:

• την αδερφή μου

Yes. Η δασκάλα specifically means the female teacher.

The masculine form is:

• ο δάσκαλος = male teacher

So in this sentence, the speaker is talking about a woman.

Also, δασκάλα μου can mean:

• my teacher in a literal educational sense and sometimes, in other contexts,
• a woman who teaches or instructs

But here it most naturally means my female teacher.

The structure is:

• Η αμφιβολία μου = subject
• φεύγει = verb
• όταν μιλάω με τη δασκάλα μου = time clause

So literally:

• My doubt goes away when I talk with my teacher.

Greek word order is flexible, so you could also say:

• Όταν μιλάω με τη δασκάλα μου, η αμφιβολία μου φεύγει.

That version sounds equally natural. The meaning stays the same; the emphasis changes slightly.

A simple pronunciation guide is:

I amfivolía mou févyi ótan miláo me ti daskála mou.

A few helpful notes:

• η sounds like ee
• αι in φεύγει does not appear here, but ει sounds like ee
• γ before ι/ε often sounds like a soft y-like sound, so φεύγει is roughly FEV-yee
• θ in όταν is like English th in think
• δ in δασκάλα is like English th in this

The stress marks matter:

• αμφιβολία
• φεύγει
• όταν
• μιλάω
• δασκάλα

Yes, but the meaning changes slightly.

• μιλάω με τη δασκάλα μου = I talk to/with my teacher
• συζητάω με τη δασκάλα μου = I discuss things with my teacher

Μιλάω is broader and more neutral. Συζητάω suggests more of a discussion or conversation about something specific. In your sentence, μιλάω sounds very natural.
