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 has special verbal morphology to indicate that the sentence is a <i>yes-no</i> question. For example, in Tunica, the verbal morpheme <i>-n</i> indicates that the sentence is a <i>yes-no</i> question, as in <i>lo’ta wi-wa’na-<b>n</b></i> ‘run 2sg-want-Q’ for ‘Do you want to run?’ (Dryer 2008).  

<br><br><b>Glossing convention:</b> Yes-No question morphemes will be glossed Q.
