Questions & Answers about استنتجت أنه لا بد أن نفتش كل المبنى.
Why does this sentence use أن after لا بد instead of أنّ or من?
The phrase لا بد is followed by أن here because it introduces an action verb (نفتش). If you were following it with a noun clause to express a strong deduction, you would use لا بد أنّ. If you were attaching a noun to express necessity, you would use لا بد من. Since we are saying it is necessary that we perform the action of searching, we use أن plus the verb.
The translation says "She deduced that...", so why does أنه have the masculine suffix ـه?
The suffix ـه in أنه acts as a dummy pronoun, often called the pronoun of the situation or fact. Because the phrase that follows (لا بد أن...) doesn't have a specific noun or pronoun to attach to أنّ, Arabic uses the default masculine singular ـه to roughly mean "She deduced that (the situation is)...".
How does the Form X verb استنتجت (she deduced) connect to its root?
The root is ن ت ج, which relates to producing or yielding, seen in the common word نتيجة (result). Form X verbs often carry the meaning of seeking, extracting, or acquiring the root's meaning. Therefore, extracting a result becomes "to deduce" or "to infer".
What happens to the ending of the verb نفتش (we search) in this sentence?
It takes the subjunctive mood because it comes immediately after the particle أن. In fully voweled Arabic, this means the final letter takes a fatha, making it نفتّشَ (nufattiša).
How does the phrase كل المبنى translate to "the whole building" instead of "every building"?
When the word كل is followed by a definite noun (a noun with ال like المبنى), it means "all of" or "the whole". If it were followed by an indefinite singular noun (كل مبنى), it would mean "every building".
