hall: [OE] Etymologically, a hall is a ‘roofed or covered place’. Its ultimate ancestor was prehistoric West and North Germanic *khallō, a derivative of *khal-, *khel- ‘cover, hide’ (a slightly different derivative produced English hell, and cell, clandestine, conceal, hull ‘pod’, and possibly colour and holster are all relatives, close or distant).

It retained much of its original meaning in Old English heall, which denoted simply a ‘large place covered by a roof’. This gradually became specialized to, on the one hand, ‘large residence’, and on the other, ‘large public room’. The main current sense, ‘entrance corridor’, dates from the 17th century (it derives from the fact that in former times the principal room of a house usually opened directly off the front door).

hall (n.)youdaoicibaDictYouDict
Old English heall "spacious roofed residence, house; temple; law-court," any large place covered by a roof, from Proto-Germanic *hallo "covered place, hall" (cognates: Old Saxon, Old High German halla, German halle, Dutch hal, Old Norse höll "hall;" Old English hell, Gothic halja "hell"), from PIE root *kel- (2) "to hide, cover, conceal" (see cell).

Sense of "passageway in a building" evolved 17c., from the time when the doors to private rooms opened onto the large public room of the house. Older sense preserved in town hall, music hall, etc., in use of the word in Britain and Southern U.S. for "manor house," also "main building of a college" (late 14c.). French halle, Italian alla are from Middle High German. Hall of fame attested by 1786 as an abstract concept; in sporting sense first attested 1901, in reference to Columbia College; the Baseball Hall of Fame opened in 1939. Related: Hall-of-famer.
