Η συνεργάτιδά μου ζήτησε άλλη μια διευκρίνιση, γιατί το email δεν ήταν αρκετά ξεκάθαρο.

This is about stress and the possessive μου.

• συνεργάτιδα normally has its stress on -ά-:
  συνεργάτιδα
• When the unstressed possessive μου comes after it, Greek often adds or preserves an extra written accent:
  η συνεργάτιδά μου

This helps show the correct pronunciation rhythm.

So:

• η συνεργάτιδα = the female colleague / associate
• η συνεργάτιδά μου = my female colleague / associate

This is very common with nouns followed by weak possessive words like μου, σου, του, της.

Examples:

• η αδελφή → η αδελφή μου
• η δουλειά → η δουλειά μου
• η συνεργάτιδα → η συνεργάτιδά μου

συνεργάτιδα usually means a female colleague, associate, collaborator, or coworker, depending on context.

It is specifically feminine.

Related forms:

• ο συνεργάτης = male colleague / associate
• η συνεργάτιδα = female colleague / associate

It can sound a little broader than English colleague. In some contexts it may mean:

• coworker
• collaborator
• business associate
• team member

So in this sentence, η συνεργάτιδά μου is most naturally my colleague or my associate, with the fact that the person is female built into the Greek word.

ζήτησε is the aorist form of ζητάω / ζητώ (to ask for, request).

Here it means:

• she asked for
• she requested

Why aorist? Because Greek uses the aorist for a completed action, seen as a whole.

So:

• ζήτησε = she asked / she requested
• ζητούσε = she was asking / used to ask

In this sentence, the speaker is referring to one completed event:

• My colleague asked for another clarification

That is why ζήτησε fits naturally.

Yes, literally it is something like another one clarification, but in natural English it means:

• another clarification
• one more clarification

Breakdown:

• άλλη = another
• μια = one / a
• διευκρίνιση = clarification

So άλλη μια is a very common Greek way to say:

• another
• one more

Examples:

• άλλο ένα λεπτό = one more minute
• άλλη μια φορά = one more time / once again
• άλλη μια ερώτηση = one more question

So άλλη μια διευκρίνιση is perfectly normal Greek.

Yes, but the nuance can be slightly different.

Both are possible:

• άλλη μια διευκρίνιση
• μια άλλη διευκρίνιση

Very generally:

• άλλη μια often emphasizes one more / an additional
• μια άλλη can more easily suggest a different one

In many contexts, though, the difference is small and both may translate as another clarification.

In your sentence, άλλη μια διευκρίνιση sounds very natural because the idea is:

• she wanted one more clarification

Because Greek often omits the indefinite article where English uses a/an, especially after certain verbs and in expressions like this.

Here:

• ζήτησε άλλη μια διευκρίνιση = she asked for another clarification

The noun διευκρίνιση is the direct object of ζήτησε, and it is in the accusative singular.

You could think of the structure as:

• ζήτησε = requested
• άλλη μια διευκρίνιση = another clarification

Greek does have an indefinite article:

• ένας / μία (μια) / ένα

But in this phrase, μια is already there as part of άλλη μια, so the noun does not need anything more.

It is accusative singular.

Why? Because it is the thing being requested, so it functions as the direct object of the verb ζήτησε.

The dictionary form is:

• η διευκρίνιση = clarification

In this noun, nominative and accusative singular look the same:

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

In the sentence, there is no article before it, so you identify the case from its role:

• subject? no
• direct object? yes
  Therefore it is accusative.

Because γιατί introduces the reason clause:

• ..., γιατί το email δεν ήταν αρκετά ξεκάθαρο.
• ..., because the email was not clear enough.

So the sentence has:

1. main clause: Η συνεργάτιδά μου ζήτησε άλλη μια διευκρίνιση
2. reason clause: γιατί το email δεν ήταν αρκετά ξεκάθαρο

In Greek, it is normal to separate that kind of explanatory clause with a comma.

Also remember that γιατί can mean both:

• because
• why

The meaning depends on context.

Examples:

• Έφυγα γιατί κουράστηκα. = I left because I got tired.
• Γιατί έφυγες; = Why did you leave?

Yes, it is very normal in modern Greek.

email is a loanword, and speakers very commonly say:

• το email

It is treated as neuter, which is common for borrowed words in Greek.

So:

• το email
• του email
• τα email or sometimes τα emails

You may also see more Greek-based alternatives, such as:

• το ηλεκτρονικό μήνυμα = the electronic message
• το ηλεκτρονικό ταχυδρομείο = email / electronic mail

But in everyday use, το email is extremely common.

ήταν is the imperfect of είμαι (to be).

So:

• είναι = is
• ήταν = was

In this sentence:

• το email δεν ήταν αρκετά ξεκάθαρο
• the email was not clear enough

The imperfect here gives a past-state meaning:

• at that time, the email was not sufficiently clear

With δεν, it becomes negative:

• δεν ήταν = was not

Here αρκετά means enough / sufficiently.

So:

• αρκετά ξεκάθαρο = clear enough / sufficiently clear

This can be tricky because αρκετά can also mean quite / rather in other contexts.

Compare:

• Δεν ήταν αρκετά ξεκάθαρο. = It was not clear enough.
• Ήταν αρκετά καλό. = It was quite good / fairly good.

So the exact translation depends on context.
In your sentence, because of the negative:

• δεν ήταν αρκετά ξεκάθαρο the natural meaning is:
• it wasn’t clear enough

Because ξεκάθαρο agrees with το email, which is neuter singular.

Greek adjectives must agree with the noun they describe in:

• gender
• number
• case

Here:

• το email = neuter singular
• so the adjective is ξεκάθαρο = neuter singular

Compare:

• ο άντρας είναι ξεκάθαρος = the man is clear
• η εξήγηση είναι ξεκάθαρη = the explanation is clear
• το email είναι ξεκάθαρο = the email is clear

That is why the ending is -ο.

Both can mean clear, but they have slightly different flavor.

• ξεκάθαρος / ξεκάθαρη / ξεκάθαρο often sounds very natural and everyday, like clear, straightforward, unambiguous
• σαφής / σαφής / σαφές can sound a little more formal or abstract, though it is also common

So:

• το email δεν ήταν αρκετά ξεκάθαρο sounds very natural in everyday Greek
• το email δεν ήταν αρκετά σαφές is also possible, but a bit more formal in tone

Greek word order is more flexible than English, though not completely free.

The neutral version here is:

• Η συνεργάτιδά μου ζήτησε άλλη μια διευκρίνιση, γιατί το email δεν ήταν αρκετά ξεκάθαρο.

But other orders are possible for emphasis, for example:

• Άλλη μια διευκρίνιση ζήτησε η συνεργάτιδά μου...
  This puts more emphasis on another clarification.
• Γιατί το email δεν ήταν αρκετά ξεκάθαρο, η συνεργάτιδά μου ζήτησε άλλη μια διευκρίνιση.
  This foregrounds the reason.

So Greek often uses word order to shift emphasis, while the endings and articles help show grammatical relationships.

You would change the feminine noun to the masculine form:

• Ο συνεργάτης μου ζήτησε άλλη μια διευκρίνιση, γιατί το email δεν ήταν αρκετά ξεκάθαρο.

Changes:

• Η συνεργάτιδά μου → Ο συνεργάτης μου

The rest of the sentence stays the same because:

• ζήτησε works for both he asked and she asked
• το email is still neuter
• ξεκάθαρο still agrees with email, not with colleague
