"Just a scosh.." long O ... is a New Englandism meaning a teeny weeny bit. At least so I thought.
Then I went to Hawaii and heard it there but thought to self "Well New England Missionaries did come here."
Then - lo and behold!
My Japanese neighbor used the word and I learned it is Japanese meaning a little bit!
Then I remembered that New England sailing ships visited Japan and stopped in Hawaii for water and fresh fruits/veggies.And there was an influx of Japanese into Hawaii in the 1800s. Then of course King Kalakaua, on a visit to Japan, suggested his daughter marry the Emporer's son but the idea came to nothing.
But that nothing to do with motion, unless you count the movement of time and the spheres and ... oh! Dear me! I am wandering too far afield ... again. Sorry!
