Ζητήσαμε μικρή παράταση για την υποβολή της αίτησης, επειδή το ίντερνετ έπεφτε όλο το πρωί.

Ζητήσαμε is the aorist form of ζητάω / ζητώ (to ask for, request). It means we asked / we requested.

Greek uses the aorist for a completed action viewed as a whole. In this sentence, the request is treated as a single completed event: we made the request.

So:

• ζητήσαμε = we asked / we requested
• not we were asking or we used to ask

Μικρή is the feminine singular form of μικρός (small, little, short), and it agrees with παράταση, which is a feminine noun.

So:

• μικρή = feminine singular adjective
• παράταση = feminine singular noun

They match in gender, number, and case.

In context, μικρή παράταση means something like:

• a short extension
• a small extension
• a brief extension

Here παράταση means extension, especially an extension of time or a deadline.

So ζητήσαμε μικρή παράταση means:

• we asked for a short extension
• we requested a little more time

It is a very natural word for formal situations like deadlines, applications, submissions, and official procedures.

Για here means for and introduces what the extension is related to.

So:

• παράταση για την υποβολή = an extension for the submission

This is a very common structure in Greek:

• παράταση για... = extension for...
• προθεσμία για... = deadline for...
• χρόνος για... = time for...

In this sentence, για την υποβολή της αίτησης means for the submission of the application.

Because the preposition για normally takes the accusative in Modern Greek.

So:

• για
  • accusative
• η υποβολή = nominative
• την υποβολή = accusative

That is why you get:

• για την υποβολή

Της αίτησης is in the genitive because it depends on υποβολή.

This is the Greek way to say:

• the submission of the application

So:

• η υποβολή = the submission
• της αίτησης = of the application

This kind of noun + genitive structure is extremely common in Greek:

• η αρχή του μαθήματος = the beginning of the lesson
• το τέλος της μέρας = the end of the day
• η υποβολή της αίτησης = the submission of the application

Yes. Greek could also use a clause with a verb, for example:

• Ζητήσαμε μικρή παράταση για να υποβάλουμε την αίτηση.

That means:

• We asked for a short extension in order to submit the application.

The version in your sentence, για την υποβολή της αίτησης, sounds a bit more formal and administrative, which fits well with words like αίτηση and παράταση.

The comma separates the main clause from the reason clause.

Main clause:

• Ζητήσαμε μικρή παράταση για την υποβολή της αίτησης

Reason clause:

• επειδή το ίντερνετ έπεφτε όλο το πρωί

So the comma works like in English before a clause giving the reason:

• ..., because ...

Greek punctuation often uses a comma in this kind of sentence.

Επειδή means because.

In many situations, επειδή and γιατί can both mean because, but there is often a slight difference in tone:

• επειδή can sound a little more neutral or formal
• γιατί is extremely common in everyday speech

So this sentence could also be said with γιατί, but επειδή fits very well in a more careful or written style.

Έπεφτε is the imperfect of πέφτω. Here it does not literally mean was falling in the physical sense. With things like internet, phone lines, or systems, πέφτω can mean:

• go down
• cut out
• drop
• stop working temporarily

The imperfect έπεφτε shows a repeated or ongoing situation in the past:

• the internet kept dropping
• the internet was going down repeatedly

If you said έπεσε, that would sound more like a single event:

• the internet went down

But έπεφτε όλο το πρωί means it was happening again and again throughout the morning.

Ίντερνετ is treated as a neuter noun in Greek, so you often see:

• το ίντερνετ

In Greek, nouns very often appear with the article when you are talking about something specific or general in a normal sentence. So το ίντερνετ έπεφτε is completely natural.

Also, ίντερνετ is basically indeclinable in everyday use, so the form usually stays the same:

• το ίντερνετ
• του ίντερνετ

Όλο το πρωί means all morning or the whole morning.

Literally:

• όλο = whole / all
• το πρωί = the morning

This is a common Greek time expression. Greek often uses the accusative in expressions of duration, so:

• όλο το πρωί = for the whole morning / all morning

Similar expressions:

• όλη μέρα = all day
• όλη νύχτα = all night
• όλο το απόγευμα = all afternoon

Yes, the order can change.

The sentence as written is:

• Ζητήσαμε μικρή παράταση..., επειδή το ίντερνετ έπεφτε όλο το πρωί.

This is very natural: first the action, then the reason.

But Greek could also say:

• Επειδή το ίντερνετ έπεφτε όλο το πρωί, ζητήσαμε μικρή παράταση για την υποβολή της αίτησης.

That puts more emphasis on the reason first.

Greek word order is fairly flexible, but the version you have sounds very natural and balanced.

Yes. Η αίτηση is a very common word for:

• application
• request form
• formal request

In this sentence, it clearly means application in an official or administrative context.

Very common combinations are:

• κάνω αίτηση = apply / submit an application
• υποβολή αίτησης = submission of an application
• φόρμα αίτησης = application form

It can mean both, depending on context.

With something like παράταση, the most natural English translation is usually:

• we requested
• we asked for

Because this is a formal object, requested often sounds especially appropriate:

• We requested a short extension...

But grammatically, ζητήσαμε is just the normal past form of ask for / request.

It sounds fairly natural but somewhat formal-neutral, mainly because of:

• παράταση
• υποβολή
• αίτηση
• επειδή

These are all common words, but together they give the sentence an administrative or semi-formal tone.

A more casual version might be something like:

• Ζητήσαμε λίγο παραπάνω χρόνο για να στείλουμε την αίτηση, γιατί το ίντερνετ έπεφτε όλο το πρωί.

Your original sentence is the kind of Greek you might see in an email, message to an office, or formal explanation.
