قست الباب قبل النقلة.

قست is the past tense, first-person singular form of the verb قاس / يقيس, meaning to measure.

So قست = I measured.

The -ت ending tells you the subject is I, so Arabic does not need a separate word like أنا unless you want extra emphasis.

This happens because قاس is a hollow verb in Arabic, meaning its middle radical behaves differently when endings are added.

In these verbs, the long vowel often shortens or disappears when you add person endings in the past tense.

For example:

• قاس → قست = I measured
• شاف → شفت = I saw
• جاب → جبت = I brought

So قست is the normal form, not a shortened version of something else.

Because the verb already includes the subject.

In قست, the ending -ت tells you that the subject is I. This is very normal in Arabic.

So:

• قست الباب = I measured the door
• أنا قست الباب = I measured the door

Both are correct, but adding أنا usually gives a bit more emphasis or contrast.

That depends on the speaker and region, especially because of the letter ق.

Possible pronunciations include:

• 'est in many urban Levantine accents, where ق becomes a glottal stop
• qest in dialects that keep ق
• gest in some regional varieties

So the word may sound different, even though it is written the same way.

Arabic often allows verb-first word order.

So:

• قست الباب = literally measured I the door
• natural meaning: I measured the door

This is normal Arabic structure. You can also say:

• أنا قست الباب

That puts the subject first and can sound a little more explicit or emphatic.

Yes. الباب is the thing being measured, so it is the direct object.

Arabic does not need a special word like English the door with extra marking such as measured the door vs measured on the door. The noun simply follows the verb as the object.

So:

• قست = I measured
• الباب = the door

Together: I measured the door.

قبل means before, and النقلة is the noun phrase that follows it.

So the structure is:

• قبل = before
• النقلة = the move / the relocation

Together:

• قبل النقلة = before the move

This is a very common way to express time in Arabic: before + noun.

النقلة usually means the move, the relocation, or sometimes the transfer depending on context.

In everyday Levantine, it can refer to things like:

• moving to a new house
• moving furniture/things
• a transfer from one place to another

It is a fairly colloquial, everyday noun. A more formal Arabic word might be something like الانتقال, but النقلة sounds more natural in casual speech.

It is definite because it refers to a specific move that both speaker and listener understand.

So النقلة means the move, not just a move.

If the situation were less specific, a speaker might use an indefinite form, but here the definite form suggests a known event, like the move we were planning.

Because ن is a sun letter.

In Arabic, when الـ comes before a sun letter, the l sound of the article is not pronounced. Instead, the next consonant is doubled.

So النقلة is written with ال, but pronounced more like:

• en-na'le
• or in-na'le

depending on the accent.

So the l is not heard, even though it is still written.

In Levantine, the final ة is usually pronounced like -e or sometimes -a, depending on the dialect.

So النقلة often sounds like:

• na'le

If another ending is attached, that ة can turn into a clear t sound. For example, with a suffix, you may hear the t appear.

So in this sentence, it is just the normal feminine noun ending.

Yes. The sentence as written is understandable, but in very natural conversation, many speakers might also say something like:

• قست الباب قبل ما ننقل
• قست الباب قبل ما تصير النقلة

Those mean roughly the same thing in context, but قبل ما + verb is often very common in everyday speech.

Still, قبل النقلة is perfectly understandable and works well if you want before the move as a noun phrase.

A simple Levantine negation would be:

• ما قست الباب قبل النقلة

That means I didn’t measure the door before the move.

In Levantine, ما before the past verb is the most common basic negation pattern.
