ghItlhpu' mayqel, jatlh:
{vIqIp'eghmoH} for "I caused him to hit himself".
is it acceptable ?
Absolutely (I believe). I'll try to explain why. The verb root {qIp} is bivalent. It can take two arguments: a subject and object. Subject {ghaH} Object {SoH} Verb form: {DuqIp} "he hits you" Adding {-'egh} reduces the verb's valency count by one, disallowing an object. Subject {ghaH} Object {SoH} ? none Verb form: {qIp'egh} "he hits himself" Adding {-moH} adds a new subject - the causer of the action - which pushes the old subject out of subject position and demotes it to the first available empty category. Since the object was deleted by {-'egh}, there is no object, meaning the object spot is now open to "catch" the old subject. Causer {jIH} ? new subject Old subject {ghaH} ? object Verb form: {vIqIp'eghmoH} "I make him hit himself" (Not that the brain goes through that process consciously, but it's a fair description of how Klingon causatives work.) Does that make sense? QeS 'utlh
