Don't move!

These are idiomatic ways to give the command "Don't move!" The word {yItaD} is used when speaking to an individual; {petaD} is used when giving the command to a group. The verb {taD} means "be frozen," and it is used here in a peculiar, though not really ungrammatical, way. Generally, when a verb describing a state of being (for example, {tuj} ["be hot"]) is used in the imperative form, the suffixes {-'egh} (reflexive suffix) and {-moH} ("cause") are used as well: {yItuj'eghmoH!} ("Heat yourself!"---that is, "Cause yourself to be hot!"), {yItaD'eghmoH!} ("Freeze yourself!"---that is, "Cause yourself to be frozen!"). When {taD} is used in the idiomatic sense of "not move," how- ever, it is treated as if a verb describing an activity, such as {yIt} ("walk"): {yIyIt!} ("Walk!").
