The word "ungirt" means to unencumber or untie, and there are several synonyms that capture this meaning. One synonym is "loosen," which refers to the action of making something less tight or restrictive. Another synonym is "unburden," which means to remove a burden or weight from something or someone. Yet another synonym is "unfetter," which refers to the act of releasing or freeing from restraint. All of these words share a common thread of releasing or removing something that was previously holding something back, making them useful for describing the action of "ungirting".
