Questions & Answers about لن نبدأ هذا الدرس اليوم.

What does لن mean here, and how is it different from لا and لم?

لن is used to negate an action in the future (or something that will not happen from now on).

• لن نبدأ... = “we will not start…”
  Compare:
• لا نبدأ... usually means “we don’t start / we do not start (habitually)” or a general negation.
• لم نبدأ... means “we did not start…” (past negation).

Does لن change the verb form after it?

Yes. لن makes the present-tense verb (المضارع) become subjunctive (منصوب).
So with full endings it’s:

• لن نبدأَ هذا الدرسَ اليومَ
  In normal unvowelled writing you won’t see the final ـَ, but it’s understood in formal grammar.

Why does the verb نبدأ start with نـ? Where is the word “we”?

In Arabic, the subject pronoun is often built into the verb. The prefix نـ on the present tense typically marks “we”.

• نبدأ = “we start”
  You can add نحن (“we”) for emphasis, but it’s not required:
• لن نبدأ نحن هذا الدرس اليوم (more emphatic)
