الفرن سخن دلوقتي، فاختي هتحط الخضار فيه بعد نص ساعة.

In Egyptian Arabic, present-tense sentences often leave out the verb to be.

So الفرن سخن دلوقتي is literally something like:

• the oven hot now

but it naturally means:

• the oven is hot now

This is very normal in Arabic. If you wanted past or future, then you would usually need a verb like كان.

Good question. In Egyptian Arabic, سخن is a common colloquial way to write the adjective hot/warm, especially in informal writing.

A few useful points:

• ساخن is the more standard/formal form.
• سخن reflects everyday Egyptian pronunciation more closely.
• In this sentence, سخن is functioning as an adjective/predicate: hot.

So here it means hot, not a past-tense verb.

Here it is best understood as an adjective/predicate meaning hot.

Why?

Because it comes after الفرن and describes its current state:

• الفرن سخن دلوقتي = The oven is hot now

In another context, سخن could be understood verbally, but in this sentence the structure clearly gives the descriptive meaning hot.

Yes. دلوقتي is a very common Egyptian Arabic word meaning:

• now
• right now
• at the moment

It is colloquial Egyptian. In Modern Standard Arabic, you would more likely see الآن.

The فـ means something like:

• so
• then
• therefore

It connects the first idea to the second:

• The oven is hot now, so my sister will put the vegetables in it...

In Arabic, short connecting words like فـ are often attached مباشرة to the next word in writing.

This is very common in informal Arabic writing.

The full, careful spelling is:

• أختي = my sister

But in casual writing, people often drop the hamza and write:

• اختي

So فاختي is basically:

• ف + أختي
• so + my sister

A more careful spelling would be:

• فأختي

It is made of:

• أخت = sister
• ـي = my

So:

• أختي = my sister

This ـي ending is a very common possessive suffix in Arabic:

• بيتي = my house
• كتابي = my book
• أختي = my sister

هتحط breaks down like this:

• هـ = future marker, like will / going to
• تحط = she puts / put

So:

• هتحط = she will put

The verb is from حط, which is a very common Egyptian verb meaning to put or to place.

Also note that the تـ here marks third person feminine singular, matching أختي.

Because this is Egyptian Arabic, not formal Standard Arabic.

In everyday Egyptian speech, حط is the normal verb for:

• put
• place

A more formal Arabic verb would be وضع, but that sounds much more formal and is not what people usually say in ordinary conversation.

Here فيه means in it.

It is made of:

• في = in
• ـه = it / him

So:

• فيه = in it

In this sentence, ـه refers back to الفرن:

• الخضار فيه = the vegetables in it
• meaning in the oven

A useful warning: فيه can also mean there is in other contexts, but not here.

It can often be understood either way in English, depending on context.

Literally:

• بعد = after
• نص = half
• ساعة = hour

So literally it is:

• after half an hour

But in natural English, this sentence might also be translated as:

• in half an hour

Both are reasonable here.

Because خضار in Egyptian Arabic is often used as a collective or mass noun meaning:

• vegetables

It behaves a bit like a category word rather than a simple countable plural.

Also, Arabic often uses الـ with generic nouns where English may or may not use the. So الخضار can still simply mean vegetables in context, not necessarily the vegetables in a very specific sense.
