To limp; move with a limping gait.

To stop marching.
In plain English: To halt means to stop moving completely and stay still right where you are.
"The driver had to halt immediately when the deer ran into the road."
Usage: Use halt to mean stopping movement completely rather than moving slowly or limping. This verb is often confused with stop when describing an abrupt end to action versus a gradual slowing down.
The word "halt" comes from Old English healtian, which originally meant "to be lame or walk with a limp." Its current meaning to stop moving developed later in Middle English when it was used as a noun before becoming a verb again.
