Question 1

Why is ما used here to mean 'did not' instead of لم?

Accepted Answer

Both ما followed by the past tense verb (ما سمعت) and لم followed by the jussive present tense (لم تسمع) mean 'did not hear'. In Modern Standard Arabic writing, لم is generally more common, but ما with the past tense is completely grammatically correct and often adds a slightly more conversational or narrative tone.

Question 2

How does the word أي (any) affect the grammar of ضجة (commotion) here?

Accepted Answer

The word أي always forms an Idafa (genitive construction) with the noun that follows it. Because of this, ضجة must be in the genitive case (majrur), ending with a double kasra. Furthermore, because أي is the direct object of the verb سمعت, it takes a fatha on its final letter (أيَّ).

Question 3

If المبنى (the building) comes after the preposition في, why doesn't it end with a kasra?

Accepted Answer

Words ending in an alif maqsura (ـى) like المبنى cannot carry physical vowel marks for pronunciation reasons. It is still grammatically in the genitive case (majrur) because of في, but its case ending is considered 'hidden' or implied.

Question 4

Why don't we hear a case ending on the subject, جارتي (my neighbor)?

Accepted Answer

Just like the building, the subject has a hidden case ending. When a noun is attached to the possessive pronoun ـي (my), the letter immediately before the pronoun must take a kasra to match the 'ee' sound. This forced kasra overrides the damma that would normally mark it as the subject.

Question 5

Does the word أمس (yesterday) change its ending based on its place in the sentence?

Accepted Answer

No, in standard Arabic, the specific word أمسِ (meaning yesterday) is fixed (mabni) and always ends with a kasra, no matter its grammatical position in the sentence.
