netop

Dictionary of American Words And Phrases by John Russell Bartlett.

"This Indian word," says Mr. Pickering, "is still used, colloquially, in some towns in the interior of Massachusetts, to signify a friend, or (to use a cant word) a crony." Roger Williams, in his Key to the Indian Language, says, "What cheer, netop? is the general salutation of all English towards the Indians."
