Mahaskakook, a boundmark in the Livingston Patent, is described, in one entry, as "A copse," _i. e._ "A thicket of underbrush," and in another entry, "A cripple bush," _i. e._ "A patch of low timber growth"--Dutch, _Kreupelbosch,_ "Underwood." Probably the Indian name has, substantially, the same moaning. _Manask_ (Del.), "Second crop"; _-ask,_ "Green, raw, immature"; _-ak,_ "wood"; _-ook_ (_ûk_), locative. The location has not been ascertained. Nachawawakkano, given as the name of a creek described as a "creek which comes into another creek," is an equivalent of _Léchau-wakhaune_ (Lenape), "The fork of a river," a stream that forks another stream. Aupaumut, the Stockbridge Historian, wrote, with locative suffix, _Naukhuwwhnauk,_ "At the fork of the streams." Mawichnauk--"the place where the two streams meet being called Mawichnauk"--means "The fork place," or place where the Nachawawakkano and the Tawastaweka came together, or where the streams meet or flow together. In the Bayard Patent the name is written Mawighanuck and Wawieghanuck. (See Wawighanuck.) Shaupook and Skaukook are forms of the name assigned to the eastern division of a stream, "which, a little lower down," was "called Twastawekah," known later as Claverack Creek. It may be translated from _Sóhk,_ Mass., "outlet," and _ûk,_ locative, "At the outlet" or mouth of the stream. Twastawekah and Tawastawekah, given, in the Livingston Patent, as the name of Claverack Creek, is described as a place that was below Shaukook, The root is _Tawa,_ an "open space," and the name apparently an equivalent of Lenape _Tawatawikunk,_ "At an open place," or an uninhabited place, a wilderness. _Tauwata-wique-ak,_ "A place in the wilderness." (Gerard.) Sahkaqua, "the south end of a small piece of land called Sahkaqua and Nakawaewick"; "to a run of water on ye east end of a certain flat or piece of land called in ye Indian tongue, Sahkahka; then south . . . one hundred and forty rods to . . . where two runs of water come together on the south side of the said flat; then west . . . to a rock or great stone on the south corner of another flat or piece of low land called by the Indians Nakaowasick." (Doc. Hist., iii, 697.) On the surveyor's map Nakaowasick, the place last named, is changed to Acawanuk. From the text, _Sahkaqua_ described "Land or place at the outlet or mouth of a stream," from _Sóhk,_ "outlet," and _-ohke,_ "land" or place. The second name _Nakawaewick_ (Nakaouaewik, Nakawasick, Acawasik) is probably from _Nashauewasuck,_ "At (or on) a place between," _i. e._ between the streams spoken of.
