Sidney Oldall Addy, The Hall of Waltheof — XIX. Some Sheffield Street-Names (1893)
“ Snig Hill, then, is "snug hill," snug street, with the meaning close, retired, narrow. In the chapter on "The House" a drawing of this street will be found showing some old houses, with projecting upper stories, and possibly all the houses in the street were once of this kind. In a street already narrow upper stories projecting a long way would give an appearance of still greater narrowness, so that such a street might on that account be called "snig" or "snug." How snug some of the streets in Sheffield once were I have already shown when speaking of the Hartshead. ”
