يمكن أن نذهب غدا.

In this sentence, يمكن means something like it is possible or it may be possible.

So يمكن أن نذهب غدًا literally looks more like:

• It is possible that we go tomorrow

But in natural English, that often becomes:

• We can go tomorrow
• It may be possible for us to go tomorrow

So يمكن does not literally mean we can by itself. It is an impersonal expression meaning it is possible.

أن is a particle that introduces a following verb, often similar to to or that depending on how you explain it.

In this sentence:

• يمكن = it is possible
• أن نذهب = that we go / for us to go

So:

• يمكن أن نذهب = it is possible for us to go

A learner will see أن very often after verbs and expressions like:

• أريد أن أذهب = I want to go
• يجب أن ندرس = we must study
• يمكن أن نذهب = we can go / it is possible for us to go

Also, after أن, the following present-tense verb is normally in the subjunctive.

In Arabic, the verb itself often includes the subject.

Here:

• نذهب = we go

The prefix نـ at the beginning of the verb marks we in the present tense.

So Arabic does not need a separate word like نحن here.

You could say:

• يمكن أن نحن نذهب غدًا

but that would be unnatural in normal MSA. The natural version is simply:

• يمكن أن نذهب غدًا

because the we is already built into نذهب.

Good question. In fully vocalized Arabic, the basic present tense often ends in ـُ:

• نذهبُ = we go

But after أن, the verb usually becomes subjunctive, and one effect is that the final ـُ changes to ـَ:

• نذهبَ

So the fully vocalized sentence would be:

• يمكن أن نذهبَ غدًا

In normal everyday writing, short vowels are usually not written, so you just see:

• يمكن أن نذهب غدا

That means the written form does not show this grammar change, but it is still there in principle.

No. Arabic can express the future in more than one way.

Here, غدًا already means tomorrow, so the future meaning is clear:

• يمكن أن نذهب غدًا = We can go tomorrow

You do not need سـ or سوف.

Compare:

• نذهب غدًا = we go tomorrow / we will go tomorrow
• سنذهب غدًا = we will go tomorrow
• سوف نذهب غدًا = we will go tomorrow

With غدًا, the time word itself already makes the meaning future.

It is pronounced ghadan in careful MSA pronunciation when fully vowelled as غدًا.

A rough guide:

• غ = a voiced guttural sound, often written gh
• د = d
• final ًا = an

So:

• غدًا ≈ gha-dan

In pause, many speakers may pronounce it more like ghadan or ghada depending on style, but in MSA grammar the full form is غدًا.

غدًا is the fully vowelled form. The ending ًا shows tanwīn fatḥ and marks it as an adverbial accusative form, which is common for time expressions.

In ordinary Arabic writing, short vowels are usually omitted, so it is often written simply:

• غدا

Both refer to the same word here.

So:

• غدًا = fully marked
• غدا = normal unvowelled spelling

Yes. That would also be correct, but it is slightly different in nuance.

• يمكن أن نذهب غدًا = it is possible that we go tomorrow / we can go tomorrow
• نستطيع أن نذهب غدًا = we are able to go tomorrow

يمكن focuses more on possibility. نستطيع focuses more on ability.

In many everyday contexts, both can translate as we can go tomorrow, but they are not identical.

No special gender marking appears here for the subject, because نذهب means we go, and we is not marked as masculine or feminine in the Arabic present-tense verb.

So this sentence can be said by:

• a group of men
• a group of women
• a mixed group

The form نذهب stays the same.

The sentence is:

• يمكن = it is possible
• أن نذهب = that we go / for us to go
• غدًا = tomorrow

So the structure is roughly:

• possible + that + we go + tomorrow

This is different from the most natural English order, but very normal in Arabic.

A very literal breakdown is:

• يمكن → it is possible
• أن → that / to
• نذهب → we go
• غدًا → tomorrow

Natural English translation:

• We can go tomorrow

Yes, depending on context.

Because يمكن expresses possibility, the sentence can sometimes be understood as:

• We can go tomorrow
• We may go tomorrow
• It may be possible for us to go tomorrow

The best English translation depends on the situation. If someone is talking about permission or opportunity, can may fit. If they are talking about possibility or uncertainty, may might fit better.

So this Arabic sentence is a little broader than a single fixed English wording.
