whether (2).
Today: “As to whether.”
In The King’s English 344 (3d ed. 1931), the Fowler brothers describe this phrasing as “seldom necessary.” That judgment still stands — e.g.:
o “Surprisingly, most folks have never taken the time to learn this skill . . . , [which] may mean the difference as to whether [read ‘determine whether’] someone with no pulse or respiration will live or die.” David Jennings, “We’re All Obligated to Learn Basic Life-Saving Techniques,” Cincinnati Post, 10 July 1997, at A20.
o “Mellot admits he ‘doesn’t have any facts’ as to [read ‘about’] whether the curfew actually has cut crime.” John Luciew, “Curfew’s Legality Still Not Precise,” Patriot & Evening News (Harrisburg), 24 Sept. 1997, at A1.
