Η στολή της συναδέλφου μου είναι απλή, αλλά πολύ πρακτική για τόσες ώρες δουλειάς.

Because Greek uses the genitive case to show possession.

• η συνάδελφος = the colleague / colleague (dictionary form, nominative)
• της συναδέλφου = of the colleague / the colleague’s

So:

• Η στολή της συναδέλφου μου = my colleague’s uniform

The word μου means my, but in Greek it often comes after the noun phrase it belongs to:

• η συνάδελφός μου = my colleague
• η στολή της συναδέλφου μου = my colleague’s uniform

So συναδέλφου is in the genitive because it depends on στολή.

The basic form is η συνάδελφος.

This is a useful noun because it looks a bit unusual:

• nominative: η συνάδελφος
• genitive: της συναδέλφου

It means female colleague here because the article is feminine: της.

In modern Greek, συνάδελφος can refer to a male or female colleague depending on context, article, and agreement.

They do different jobs.

• της is the genitive article: it marks συναδέλφου as genitive feminine singular.
• μου is the possessive pronoun: my

So:

• της συναδέλφου = of the colleague
• της συναδέλφου μου = of my colleague

Greek often builds possession this way:

• το βιβλίο του φίλου μου = my friend’s book
• literally: the book of the friend my

This is completely normal in Greek.

Because they describe η στολή, and στολή is a feminine singular noun.

So the adjectives must agree with it:

• η στολή — feminine singular
• απλή — feminine singular
• πρακτική — feminine singular

This agreement is very important in Greek. Adjectives change form to match the noun in gender, number, and case.

Because πολύ here is an adverb, meaning very.

• πολύ πρακτική = very practical

When πολύ works as an adverb, it does not change form.

Compare:

• πολύ πρακτική = very practical → adverb
• πολλή δουλειά = a lot of work → adjective/determiner, so it agrees with the noun

So in this sentence, πολύ modifies the adjective πρακτική, not a noun.

Αλλά means but.

It links two contrasting ideas:

• είναι απλή = it is simple
• αλλά πολύ πρακτική = but very practical

So it works just like English but.

Because Greek, like English, does not need to repeat the verb here.

• είναι απλή, αλλά πολύ πρακτική

This is like English:

• It is simple, but very practical

You could think of the second part as understood:

• είναι απλή, αλλά (είναι) πολύ πρακτική

But repeating είναι would usually sound unnecessary in this sentence.

This phrase means something like for so many hours of work.

It breaks down like this:

• για = for
• τόσες ώρες = so many hours
• δουλειάς = of work

So the idea is that the uniform is practical for many hours spent working.

This is a natural Greek way to express the idea.

Because it agrees with ώρες, which is feminine plural.

• η ώρα = hour
• ώρες = hours

So:

• τόση ώρα = so much time / such a long time (singular, depending on context)
• τόσες ώρες = so many hours (feminine plural)

Again, Greek agreement is the key: the word has to match the noun it goes with.

Because Greek often uses the genitive after a noun to mean of ...

• ώρες δουλειάς = hours of work

This is similar to:

• ένα ποτήρι νερού = a glass of water
• μια μέρα ξεκούρασης = a day of rest

So δουλειάς depends on ώρες and tells you what kind of hours they are: work hours.

Yes. That would also be correct and slightly more formal.

• δουλειά = everyday word for work
• εργασία = more formal or more neutral word for work/labor/task

So:

• για τόσες ώρες δουλειάς sounds natural and everyday
• για τόσες ώρες εργασίας sounds a bit more formal

Greek uses the definite article very often, including in places where English may or may not use the.

Here, Η στολή means the uniform, and then the following phrase identifies whose uniform it is:

• Η στολή της συναδέλφου μου = my colleague’s uniform

In Greek, this structure is very normal: article + noun + genitive phrase.

Not exactly. Στολή usually means uniform or a specific outfit worn for work, school, or an official role.

So it is more specific than:

• ρούχα = clothes
• φόρεμα = dress
• ντύσιμο = outfit / way of dressing

In this sentence, στολή suggests a work uniform or professional outfit.

The word order is quite natural.

• Η στολή της συναδέλφου μου = the subject
• είναι = the verb
• απλή, αλλά πολύ πρακτική = predicate adjectives
• για τόσες ώρες δουλειάς = extra phrase explaining in what sense it is practical

Greek word order is more flexible than English, but this sentence is a very standard neutral order.

The accents show which syllable is stressed.

For example:

• στολή → stress on the last syllable
• συναδέλφου → stress on δέλ
• πρακτική → stress on κή

Stress matters in Greek pronunciation and is always written. It can also help you recognize different forms of a word.

Yes. Depending on context, απλή can mean:

• simple
• plain
• uncomplicated

In this sentence, it probably suggests that the uniform is not fancy or elaborate, but that is contrasted with very practical. So simple/plain is probably the most natural feeling here.

Both, but in different parts.

• απλή comments on the appearance/design: simple, plain
• πολύ πρακτική comments on the usefulness/function

So the sentence contrasts looks with practicality:

• it may not be stylish or elaborate,
• but it works well for long working hours.
