interrogativo

Mood is a feature that expresses modality and subclassifies finite verb forms. The indicative can be considered the default mood. A verb in indicative merely states that something happens, has happened or will happen, without adding any attitude of the speaker. The conditional mood is used to express actions that would have taken place under some circumstances but they actually did not / do not happen. Grammars of some languages may classify conditional as tense (rather than mood) but e.g. in Czech it combines with two different tenses (past and present). The subjunctive mood is used under certain circumstances in subordinate clauses, typically for actions that are subjective or otherwise uncertain. In German, it may be also used to convey the conditional meaning. The quotative mood is used e.g. in Estonian to denote direct speech. The boundary between this mood and the non-first-hand Evident iality is blurred. The necessitative mood expresses necessity and corresponds to the modal verbs “must, should, have to”: “He must come .” Verbs in some languages have a special interrogative form that is used in yes-no questions. This is attested, for instance, in the Turkic languages. Celtic languages have it for the copula but not for normal verbs. Expresses surprise, irony or doubt. Occurs in Albanian, other Balkan languages, and in Caddo (Native American from Oklahoma).
