The <b>prohibitive</b> is a negative imperative, as in English <i>Don't do that!</i> 

<br><br>A ‘yes’ value indicates that the language in question forms prohibitives by adding a special, non-sentential negation morpheme to a form of the verb which is used for the imperative. Vietnamese is such a language. For example, the imperative <i>Uông ruou!</i> ‘drink alcohol’ is negated with the special negation form <b><i>chó</i></b>, as in <i><b>Chó </b>uông ruou!</i> ‘Don’t drink alcohol’. This is in contrast to sentential negation, which is marked with <b><i>không</i></b>, as in <i><b>không</b> uông ruou</i>, ‘You are not drinking alchohol’ (van der Auwera et al. 2008). 

<br><br>Some languages have more than one prohibitive strategy. In such cases, languages are marked ‘yes’ for each prohibitive strategy used.
