The name Singac is believed to be an interpretation of the Lenape words meaning "backbone of mountain"[17][18] or that it may originate from the Lenape term schinghacki meaning "flat country" or from schingask meaning "boggy meadow", which alludes to how the area floods after a storm.[19]

"Singack - A neighborhood about five miles southwest of Paterson; it is commonly called by the old people, 'The Singack.' The name is from schinghacki, a flat country, whence is derived schingask, a boggy meadow. The name given to this neighborhood describes it accurately; it is a flat country along the Passaic river and is frequently overflowed in times of freshet."
