An '''indirect question''' (or more linguistically, '''embedded interrogative''' or '''interrogative content clause''') is a subclause that looks like a question.
An '''indirect question''' (or more linguistically, '''embedded interrogative''' or '''interrogative content clause''') is a subclause that looks like a question.


In Toaq, this is a {{tone|5}} [[content clause]] starting with {{t|}} (if/whether), or containing a question word like {{t|}} (which?) or {{t|}} (this or that?).
In Toaq, this is a {{tone|3}} [[content clause]] starting with {{t|}} (if/whether) or {{t|tïo}} (how much), or containing a question word like {{t|}} (which?) or {{t|}} (this or that?).

* The theory that top-level questions (''Which boat is yours?'') are reduceable to an imperative statement with an indirect question (Bring it about that I know which boat is yours!) is known as the '''imperative-epistemic theory of wh-questions''', and seems to be pretty widely accepted.

* The issue that questions that happen to have the same answer shouldn't be considered equivalent (e.g. I know which boat is his vs. I know who owns the SS Toaq), is known as the '''problem of convergent knowledge'''.

== Semantics ==
A popular starting point is that an indirect question denotes a set of possible answers, correct or not:
<blockquote>
⟦{{t|ꝡä tıshaı hí}}⟧ = {‘{{t|tıshaı mí A}}’, ‘{{t|tıshaı mí B}}’, ‘{{t|tıshaı mí C}}’, …}
</blockquote>
=== Exhaustivity ===
The first question is: what counts as an answer? When we say “I know who left”, what knowledge are we purporting to have?
There are various levels of '''exhaustivity''' one could demand of an answer. Suppose that only A and B left. Then increasingly exhaustive answers to the question “who left” are the following:
# '''Mention-some answers''': ‘A left’
# '''Weakly-exhaustive answer''': ‘A left and B left’
# '''Strongly-exhaustive answer''': ‘A left and B left, and no one else left.’
=== Predicates ===
How can the second slot of {{t|dua}} accept both a regular content clause, which denotes a proposition, and an interrogative clause that denotes a whole set of propositions? Doesn't this make {{t|dua}} polysemous?
There are a few possible answers to this question:
* Maybe {{t|dua}} is really a family of predicates, and {{t|dua}}<sub>P</sub> “to know a fact” is a different predicate from {{t|dua}}<sub>Q</sub> “to know the answer to a question”, and Toaq's grammar selects the right one automatically.
* Maybe {{t|dua}} in its purest form takes propositions, and there is some reduction from question complements to proposition complements. This is '''Q-to-P reduction'''.
* Maybe {{t|dua}} in its purest form takes questions, and there is a '''P-to-Q reduction'''.
The Wataru Uegaki (2019) paper in [[#See also]] is all about this.
