them are seersuckers.. (one word) from persian, (via french) for a fabric of ripples and smooth woven stripes, (often in pale colors like blue and white, or green and white, tan and white, etc) the sucker part is from sucre.. the fabric was thought to resemble milk and sugar-- the persian word for sugar was based on the grit/gravelly nature, shingle (roof, or rocky 'sand bar' (UK)) are from the same root word (these too are gravelly!)




According to the AHD, it came via Hindi, not French:
Quote:

Hindi srsakar, from Persian shroshakar : shr, milk (from Middle Persian) + o, and (from Middle Persian u, from Old Persian ut) + shakar, sugar (from Sanskrit arkar, from the resemblance of its smooth and rough stripes to the smooth surface of milk and bumpy texture of sugar).
