Massachusetts [SEP] Etymology
The Massachusetts Bay Colony was named after the indigenous population, the Massachusett, whose name likely derived from a Wôpanâak word "muswachasut", segmented as "mus(ây)" "big" + "wach8" "mountain" + "-s" "diminutive" + -"ut" "locative" (the '8' in these words refers to the 'oo' sound according to the Wôpanâak orthographic chart). It has been translated as "near the great hill", "by the blue hills", "at the little big hill", or "at the range of hills", referring to the Blue Hills, or in particular the Great Blue Hill, which is located on the boundary of Milton and Canton. Alternatively, "Massachusett" has been represented as "Moswetuset"—from the name of the Moswetuset Hummock (meaning "hill shaped like an arrowhead") in Quincy, where Plymouth Colony commander Myles Standish (a hired English military officer) and Squanto (a member of the now disappeared Patuxet band of the Wampanoag peoples) met Chief Chickatawbut in 1621.
