نبقى هنا حتى يبدأ يوم الانتقال.

نبقى is the 1st person plural imperfect form of the verb بقي, which means to remain or to stay.

So نبقى means we remain / we stay.

A helpful breakdown:

• نـ = marks we
• the rest of the verb comes from بقي

It is usually pronounced nabqā.

Because Arabic verbs usually already include the subject.

In نبقى, the prefix نـ tells you the subject is we. So Arabic does not need نحن here.

You could say نحن نبقى هنا for emphasis, but it is not necessary.
Without emphasis, نبقى هنا is perfectly normal.

Formally, نبقى is in the imperfect, which can express:

• present
• future
• habitual action

Arabic does not always separate present and future as strictly as English does.

In this sentence, because of the context with حتى and the following event, English often translates it with a future sense, such as we will stay here until.... But the Arabic form itself is still the imperfect.

Here, حتى means until.

It sets the time limit for the action:

• نبقى هنا = we stay here
• حتى يبدأ يوم الانتقال = until moving day begins

So حتى connects the main action to the point where that action stops or changes.

Yes. After حتى meaning until, if the verb refers to a future event, the imperfect verb is commonly understood as being in the subjunctive.

So in fully vowelled Arabic, this would be:

حتى يبدأَ

But in normal unvowelled writing, يبدأ looks the same whether you mean:

• يبدأُ (indicative)
• يبدأَ (subjunctive)

So the special grammar is there, but you usually do not see it in ordinary spelling.

Because the subject is يوم الانتقال, which is singular and masculine.

• يوم = day
• it is a singular masculine noun

So the verb must also be singular masculine:

• يبدأ = it begins

In Arabic, verbs agree with their subjects in gender and number. Here the subject is not days or events; it is one day.

Because verb + subject order is very common in Arabic, especially in formal written Arabic.

So:

• يبدأ يوم الانتقال = literally begins the day of the move

This sounds normal in Arabic.

You could also find يوم الانتقال يبدأ in some contexts, but verb first is very standard and natural in MSA.

يوم الانتقال is an iḍāfa construction, often called a possessive or noun-linked phrase.

It literally means:

• day of the move / transfer / relocation

In an iḍāfa:

• the first noun usually does not take الـ
• the second noun can be definite, and that makes the whole phrase definite

So:

• يوم = day
• الانتقال = the move / the transfer / the relocation

Together:

• يوم الانتقال = the day of the move, or more naturally, moving day

Not always.

الانتقال comes from a root related to moving or transitioning, and depending on context it can mean:

• move
• relocation
• transfer
• transition

In this sentence, a natural translation might be:

• moving day
• the day of relocation
• the transfer day

The exact English choice depends on the context you were given.

Because هنا already means here and functions as an adverb of place.

So Arabic simply says:

• هنا = here

You do not normally say في هنا for standard Arabic here in this kind of sentence.

So:

• نبقى هنا = we stay here

This is the normal structure.

A helpful pronunciation is:

nabqā hunā ḥattā yabdaʾa yawm al-intiqāl

A few notes:

• نبقى = nabqā
• هنا = hunā
• حتى = ḥattā
• يبدأ = yabdaʾa
• الانتقال = al-intiqāl

In normal pause, some final short vowels may not be fully pronounced, but this pronunciation is a useful careful reading form.
