Laxgalts'ap has come to mean "a dwelling place situated upon an ancient dwelling place" [Lax/ on; gal/ empty, uninhabited; ts'ap/ village]. Gitxat'in was the original name of this village before it was destroyed by fire, after which it became known as Laxgalts'ap. "Galts'ap" has also become the more widely used term today to mean "village site" (advice from Sim'oogit Gilaxnamk'ap, 1983)
