ch)
KEY NOUN: New England

- A lull in a high windstorm.
ETYMOLOGY:Variant of
slack1Regional Note: In New England a
slatch can be a lull between breaking waves or a lull in a high windstorm. Its use is recorded as far back as the 17th century:
"Whan it hath beene a sett of foule weather and that there comes an Interim . . . of faire weather . . . they call it a little Slatch of faire weather" (Nomenclator Navalis). Occurrence of the word in both its senses, formerly in Britain and now in New England, attests continuous use down through the centuries of the Old English word
slæc, which is pronounced today as it was in Old English.
Slæc is also the source of modern
slack, the relationship of
slatch and
slack being evidenced in the use of
slatch in 17th-century nautical parlance to denote the slack part of a rope or cable on a ship.
