"ghoqwI' lumuHta'."

[JamesTWils]

Can there be an unintentional execution?

[jdmcowan]

Sure. Maybe you were just threatening to execute him to try to get him to talk, but accidentally actually executed him.

[JamesTWils]

That makes perfect sense; you should be a writer, if you are not.

[LeeGOgletree]

I put, "They have executed spies." That's right... right?

[jdmcowan]

Unfortunately, that is not a possible interpretation of this sentence. The lu- prefix is only used when the subject is plural ("they") and the object is singular ("he/she/it"). So there can only be one spy executed if using the lu- prefix. To say, "They have executed spies," you would use the null prefix (the absence of a prefix): ghoqwI' muHta'.. Note that this sentence could be interpreted as, "They have executed spies," "he/she/it has executed spies," "he/she/it has executed a spy." But, the variation it can't mean is, "they have executed a spy," which must use the lu- prefix.
