Μην ανησυχείς, θα τα καταφέρεις.

Because μην is used for negative commands and prohibitions.

• Μην ανησυχείς = Don’t worry
• Δεν ανησυχείς would mean something like you are not worrying, which is a statement, not a command.

So:

• δεν negates facts/statements
• μη(ν) negates commands, wishes, and certain subjunctive-type forms

The final -ν in μην appears before a vowel or certain consonants and is very common in standard Greek.

Ανησυχείς is the 2nd person singular form of ανησυχώ / ανησυχάω = to worry.

Here it means you worry, but with μην it becomes a negative command:

• Μην ανησυχείς = Don’t worry

This is the form you use when speaking to one person informally.

Related forms:

• ανησυχώ = I worry
• ανησυχείς = you worry
• ανησυχεί = he/she/it worries

In Modern Greek, negative commands are usually formed with μη(ν) + a verb form that looks like the present subjunctive / dependent form, rather than with a special negative imperative.

So instead of a separate negative imperative form, Greek says:

• Μην ανησυχείς = Don’t worry
• Μην πας = Don’t go
• Μην το κάνεις = Don’t do it

So yes, it functions as a command, even if the form may look unfamiliar to an English speaker.

Θα is the particle used to form the future in Modern Greek.

• θα τα καταφέρεις = you will manage / you will succeed / you’ll pull it off

It is followed by a dependent verb form rather than an old-style future tense ending. In modern usage, θα is the normal way to express the future.

Examples:

• Θα έρθω = I will come
• Θα δεις = you will see
• Θα τα καταφέρεις = you will manage

It comes from καταφέρνω, which often means to manage, to succeed, or to accomplish something.

In this sentence:

• θα τα καταφέρεις = you will manage / you’ll succeed

The form καταφέρεις is the 2nd person singular form used after θα.

So:

• καταφέρνω = I manage / succeed
• θα καταφέρω = I will manage
• θα καταφέρεις = you will manage

This is one of the most common learner questions, because τα here does not translate neatly word-for-word.

In the expression τα καταφέρνω, the τα is part of the idiomatic phrase. The whole expression means:

• manage
• cope
• succeed
• pull it off

So:

• τα καταφέρνω = I manage / I make it
• δεν τα καταφέρνω = I can’t manage / I’m not succeeding
• θα τα καταφέρεις = you will manage / you’ll make it

You should learn τα καταφέρνω as a set phrase, not as a fully literal combination.

Usually it means to manage, to succeed, or to cope, depending on context.

For example:

• Τα κατάφερα! = I did it! / I made it!
• Δεν τα καταφέρνω με τα μαθηματικά. = I can’t manage math / I’m not good at math
• Θα τα καταφέρεις. = You’ll manage / You’ll be fine / You’ll succeed

So the exact English translation depends on the situation, but the core idea is handling something successfully.

The ending -εις is a very common 2nd person singular ending in Modern Greek.

Here are some examples:

• φέρνεις = you bring
• ξέρεις = you know
• κάνεις = you do
• καταφέρεις = you manage / you will manage (after θα)

So if you are talking to one person informally, -εις is a very normal ending to see.

It is informal singular, because both verbs address one person in the familiar you form.

• ανησυχείς = you worry
• καταφέρεις = you will manage

If you were speaking formally to one person, or to more than one person, Greek would normally use plural forms:

• Μην ανησυχείτε, θα τα καταφέρετε.

That can mean:

• Don’t worry, you will manage (formal singular)
• Don’t worry, you all will manage (plural)

Yes, absolutely. It is a very common everyday expression.

By itself:

• Μην ανησυχείς. = Don’t worry.

You can then add reassurance, like:

• Μην ανησυχείς, όλα θα πάνε καλά. = Don’t worry, everything will go well.
• Μην ανησυχείς, θα τα καταφέρεις. = Don’t worry, you’ll manage.

A simple pronunciation guide is:

Min anisihís, tha ta kataféris.

A few notes:

• Μην sounds like meen
• χ in ανησυχείς is a throaty sound, not like English ch
• θα sounds like tha in that, but without the final t
• stress matters in Greek:
  • ανησυχείς
  • καταφέρεις

So the rhythm is roughly:

min a-ni-si-HIS, tha ta ka-ta-FE-ris

Yes, sometimes you will see μη and sometimes μην. In this sentence, μην ανησυχείς is the standard form because the next word begins with a vowel.

In practice:

• μην ανησυχείς is the expected form here
• μη ανησυχείς may be heard or seen, but μην is the safer standard choice before a vowel

So for learners, it is best to use:

• Μην ανησυχείς

It sounds warm, encouraging, and reassuring.

It is something you would say to someone who is:

• nervous
• doubtful
• stressed
• afraid they might fail

It is very natural Greek and feels like:

• Don’t worry, you’ll manage
• Don’t worry, you can do it
• Don’t worry, you’ll be fine

The exact English wording can vary, but the emotional tone is supportive.
