Ο υπεύθυνος τμήματος ρωτάει για τη συνέπεια στα μαθήματα.

Both can be correct, but they are slightly different in style.

• Ο υπεύθυνος τμήματος is a common, compact way to say the person responsible for a department / department manager / department head.
• Ο υπεύθυνος του τμήματος means more literally the person in charge of the department.

So:

• υπεύθυνος τμήματος = a job title or fixed expression
• υπεύθυνος του τμήματος = the responsible person of that specific department

Greek often uses this kind of article-less genitive in titles and roles:

• διευθυντής σχολείου = school principal
• καθηγητής πανεπιστημίου = university professor

τμήματος is in the genitive singular.

The basic noun is:

• το τμήμα = the department

Its singular forms are:

• nominative: το τμήμα
• genitive: του τμήματος
• accusative: το τμήμα
• vocative: τμήμα

In υπεύθυνος τμήματος, the genitive shows a relationship like of the department. English often uses of or a noun-noun combination:

• head of department
• department manager

So τμήματος tells you what kind of υπεύθυνος this person is.

Originally, υπεύθυνος is an adjective meaning responsible. But very often in Greek it is also used like a noun to mean:

• the person in charge
• the supervisor
• the responsible person

Here it functions as a noun:

• Ο υπεύθυνος τμήματος = the department manager / the person in charge of the department

This is very common in Greek: adjectives can act as nouns when the article makes the meaning clear.

The article Ο means the and shows that we are talking about a specific person:

• Ο υπεύθυνος = the person in charge
• ένας υπεύθυνος = a person in charge / a manager

Greek uses the definite article very often, including before job titles and roles.

Yes, both are possible.

• ρωτάει
• ρωτά

Both mean he/she asks.

This is a common variation in Modern Greek, especially with verbs in -άω / -ώ. In everyday language, both forms are heard and understood.

For example:

• μιλάει / μιλά = he/she speaks
• ρωτάει / ρωτά = he/she asks

ρωτάει may sound a bit fuller or slightly more explicit in some contexts, but both are standard.

The verb form ρωτάει is third person singular, so it means:

• he asks
• she asks
• sometimes it asks, depending on context, though not here

Since the subject is Ο υπεύθυνος τμήματος, we understand it as:

• The department manager asks...

Greek verbs usually show the person and number, so the subject can often be omitted. But here it is stated explicitly.

Here για means about.

So:

• ρωτάει για... = asks about...

Examples:

• Ρωτάω για το πρόγραμμα. = I ask about the schedule.
• Ρωτάει για τη συνέπεια. = He/She asks about punctuality/consistency.

Be careful: Greek can also use ρωτάω κάποιον meaning I ask someone:

• Ρωτάω τον μαθητή. = I ask the student.

So:

• ρωτάω κάποιον = ask someone
• ρωτάω για κάτι = ask about something

Because συνέπεια is the object of για, so it appears in the accusative form.

The noun is:

• nominative: η συνέπεια
• accusative: τη(ν) συνέπεια

After many prepositions in Modern Greek, the following noun phrase is in the accusative:

• για τη συνέπεια
• σε ένα μάθημα
• με τον καθηγητή

So για τη συνέπεια means about punctuality / about consistency.

Both are correct spellings/forms in actual usage, but this is about pronunciation and standard writing habits.

The full accusative feminine article is:

• την

But when the next word starts with certain consonants or in everyday pronunciation, the final -ν may be dropped:

• τη συνέπεια
• την τάξη

A simple learner rule:

• Keep -ν before vowels and certain consonants for smoother pronunciation.
• It is often dropped before other consonants.

Since συνέπεια starts with σ, τη συνέπεια is perfectly normal.

It can mean both, depending on context.

συνέπεια has a broad meaning connected with being reliable, regular, and doing what is expected. In a school or class context, it often means:

• punctuality
• regular attendance
• being consistent in one’s obligations

In στα μαθήματα, the most natural sense is probably something like:

• consistency in attending classes
• punctuality in classes
• regularity with classes

So the exact English translation may vary depending on the wider situation.

στα is a contraction of:

• σε + τα = στα

So:

• στα μαθήματα literally means in the lessons/classes or at classes

The noun is:

• το μάθημα = lesson / class / course

Plural:

• τα μαθήματα = lessons / classes / courses

After σε, Greek commonly uses these contracted forms:

• σε + το = στο
• σε + τη(ν) = στη(ν)
• σε + τα = στα
• σε + τους = στους
• σε + τις = στις

Because the sentence refers to classes/lessons in general, not just one lesson.

• στο μάθημα = in the class / in the lesson
• στα μαθήματα = in classes / in lessons

Using the plural suggests a broader issue such as attendance, punctuality, or consistency across someone’s classes generally.

No, Greek word order is more flexible than English, because case endings and verb forms carry a lot of information.

The neutral order here is:

• Ο υπεύθυνος τμήματος ρωτάει για τη συνέπεια στα μαθήματα.

But other orders are possible for emphasis, for example:

• Για τη συνέπεια στα μαθήματα ρωτάει ο υπεύθυνος τμήματος.
• Ο υπεύθυνος τμήματος για τη συνέπεια στα μαθήματα ρωτάει.

These alternatives may sound more marked or stylistic. The original order is the most natural and straightforward for a learner.

A helpful approximate pronunciation is:

O ipef-thi-nos tmi-ma-tos ro-TA-ee ya ti si-NE-pya sta ma-THI-ma-ta

A few useful sound notes:

• υ here sounds like i
• εύ in υπεύθυνος sounds roughly like ef
• θ is like th in think
• για sounds like ya
• αι in ρωτάει sounds like e/i in Modern Greek pronunciation

The stress falls on:

• υπεύθυνος
• τμήματος
• ρωτάει
• συνέπεια
• μαθήματα

Yes. Depending on context, natural translations include:

• The department manager asks about punctuality in classes.
• The department head asks about consistency in attending classes.
• The person in charge of the department asks about attendance regularity in class.

Greek often allows a little range in English translation because words like συνέπεια and μαθήματα can cover slightly different shades of meaning depending on context.
