One possible derivation of the name for the island of Manhattan is from "manahachtanienk," meaning "place of general inebriation" in the Munsee dialect of Lenape. There is an associated tradition that Henry Hudson once preferred his liquor to an Indian chief on the island, and the Indian chief passed out, awaking to request more for his tribe, whereat they all got wasted.
Other possible derivations include "manahatouh" (place where timber is procured for bows and arrows)
or "menatay" (island).
Or "manhattan" may be translatable as "island of many hills."
