Question 1

Why is the verb يغب missing its middle vowel? Shouldn't it be يغيب?

Accepted Answer

Because it follows لم, which puts the verb into the Jussive mood. The regular present tense is يغيب, but the Jussive mood puts a sukun (a no-vowel marker) on the final letter ب. This creates a clash with the long vowel ي right before it. To fix this double-sukun problem, Arabic drops the weak middle letter, making it يغب.

Question 2

Even though the translation is 'was not absent' (past tense), why are we using a present tense verb form like يغب?

Accepted Answer

The negative word لم always takes a present tense verb, but it completely changes the meaning of the phrase to the past tense. So, لم يغب uses a present tense verb structure but translates to 'he was not absent' or 'he did not attend'.

Question 3

I sometimes see دون instead of بدون. What is the difference?

Accepted Answer

They both mean 'without' and are highly interchangeable. بدون just adds the prefix بـ (with/by) to دون, literally meaning 'with a lack of'. Both are extremely common in Modern Standard Arabic.

Question 4

What happens to the pronunciation at the end of the word عذر in this sentence?

Accepted Answer

The word بدون acts like a preposition, so it forces the noun following it into the genitive case. Since عذر is indefinite (meaning 'an excuse', not 'the excuse'), it takes a double Kasra ('in' sound) at the end, so it is pronounced عذرٍ ('udhrin).
