Editing Question (section)

=== Open questions ===
Open questions are formed by the use of [[interrogative word]]s such as, in English, ''when'', ''what'', or ''which''. These stand in as variables representing the unknown information being sought. They may also combine with other words to form interrogative phrases, such as ''which shoes'' in:

:Which shoes should I wear to the party?

In many languages, including English and most other European languages, the interrogative phrase must (with certain exceptions such as [[echo questions]]) appear at the beginning of the sentence, a phenomenon known as [[wh-fronting]]. In other languages, the interrogative appears in the same position as it would in a corresponding declarative sentence (''in situ'').<ref>{{cite book|chapter=Chapter 93: Position of Interrogative Phrases in Content Questions|chapter-url=http://wals.info/chapter/93|title=World Atlas of Language Structures|author-first1=Matthew S. |author-last1=Dryer|year=2013|editor-last1=Dryer|editor-first1=Matthew S. |editor-last2=Haspelmath|editor-first2=Martin|access-date=15 April 2021}}</ref>

A question may include multiple variables as in:

:Whose gifts are in which boxes?
