A <i>yes-no</i> question is a question that can be answered by either <i>yes</i> or <i>no</i>.

<br><br>A 'yes' value indicates that the language changes word order to indicate that the sentence is a <i>yes-no</i> question. English is an example, where an auxiliary moves to the front of the sentence to indicate a question, as in <i>Will you run?</i> versus <i>You will run</i>. See Dryer (2008) for discussion.
