hull: [OE] The notion underlying the word hull is of ‘covering’ or ‘concealing’. It originally meant ‘peapod’ – etymologically, the ‘covering’ of peas – and comes ultimately from the same Indo- European source as produced English cell, clandestine, conceal, hall, hell, and possibly colour and holster. It is generally assumed that hull ‘main body of a ship’, which first appeared in the 15th century, is the same word (a ship’s hull resembling an open peapod), although some etymologists have suggested that it may be connected with hollow. => cell, clandestine, conceal, hall, hell, occult
hull (n.1)
"seed covering," from Old English hulu "husk, pod," from Proto-Germanic *hulus "to cover" (cognates: Old High German hulla, hulsa; German Hülle, Hülse, Dutch huls). Figurative use by 1831.
hull (n.2)
"body of a ship," 1550s, perhaps from hull (n.1) on fancied resemblance of ship keels to open peapods (compare Latin carina "keel of a ship," originally "shell of a nut;" Greek phaselus "light passenger ship, yacht," literally "bean pod;" French coque "hull of a ship; shell of a walnut or egg"). Alternative etymology is from Middle English hoole "ship's keel" (mid-15c.), from the same source as hold (n.).
hull (v.)
"to remove the husk of," early 15c., from hull (n.1). Related: Hulled, which can mean both "having a particular kind of hull" and "stripped of the hull."
