Prohibitions are constructed like 2SG assertives, i.e. using the subject pronoun, which does not appear in the imperative. However, in prohibitions, the particle expressing negation is not placed between subject pronoun and verb (like in 2SG assertives), but precedes the subject pronoun, literally [not you laugh] 'Don’t laugh!’ (assertive: [you not laugh], [you do not laugh]).
