Apologising once more in advance for quoting boQwI', I need to bring this up, because there I read that..

"Even though tkd says that {-be'} cannot be used with imperatives, it seems that this means only that it cannot be used to form negative imperatives. For example, a sentence such as {HIleghbe'moH} seems to be possible"

I can't understand this. Isn't the {HIleghbe'moH} a negative imperative ? Doesn't it mean "make me not see !" ?

boQwI' is wrong. I don't know how the creator came to that conclusion. It would be convenient if we could, but TKD prohibits it and I don't think we've ever seen a counterexample.

Without that convenience, we have to say things like jIleghbe' 'e' yIqaSmoH cause me not seeing to occur! or be more direct: mInwIj tIvel cover my eyes! or pa' yIHurghmoH make the room dark!
