TKD: This negative suffix implies not merely that something is not done (as does -be'), but that there is a change of state: something that was previously done is now undone. For convenience, it will here be translated as undo, but it is closer to the English prefixes mis-, de-, dis- (as in misunderstand, demystify, disentangle). It is also used if something is done wrongly. Unlike -be', -Ha' can be used in imperatives.
