Naut. Also 7, 9 fack. [Of obscure origin; cf. FAKE v.1
The MHG. vach had the sense fold in addition to those of appointed place, portion of space or time, compartment; if a similar sense belonged to the etymological equivalents OE. fæc (recorded in sense space of time), MDu. vak (enclosure, partition), the word might come from either source. If it be identical with the Sc. FAIK sb. fold, a native origin seems probable.]
