Questions & Answers about Dudo que hayan leído el documento nacional.

Why is nacional placed after documento, and could I say el nacional documento instead?

Nacional is a relational adjective here, meaning it classifies the document rather than describing a subjective quality. Relational adjectives must strictly follow the noun they modify, so el nacional documento is incorrect.

Could I emphasize the adjective in this sentence by saying el documento muy nacional?

No. Because nacional is a relational adjective used to classify the document into a specific category, it cannot take degree modifiers like muy (very) or bastante (quite). In Spanish grammar, a document either is national or it isn't.

Why does this sentence use hayan instead of han?

The main verb dudar (to doubt) expresses uncertainty, which is a classic trigger for the subjunctive mood in the clause that follows. Therefore, we must use the present subjunctive form of haber (hayan) to form the present perfect subjunctive, rather than the indicative (han).

Why does the past participle leído have an accent mark?

The accent mark is needed to prevent a diphthong. In leído, the strong vowel e and the weak vowel i are next to each other. Without the accent, they would blend into one syllable. Placing the accent over the í ensures it is pronounced as its own distinct syllable.
