Ha cunin - Don't eat

When you want to order someone not to do something, you say,

Ha + base form of verb + in

For example

Ha + cun + in = Ha cunin (Don't eat)

Ha qorin = Don't write
Ha galin = Don't enter
Ha dilin = Don't kill

However, many verb change their sounds when they are used in this way,

bax >  Ha bixin = Don't go out
tag>    Ha tegin = Don't go
dheh> Ha dhihin = Don't say anything

If it is a Conj.2 or Conj,3 verb, then add 'nin'

sameyn >   Ha sameynnin = Don't do (that)
weydii>      Ha weydiinnin = Don't ask
noqo>        Ha noqonnin   = Don't come back
joogso>     Ha joogsannin = Don't stop
dheygeyso>Ha dhegeysannin = Don't listen
