VN’s favourite was Webster’s Second. W III got rid of all those obsolete words that we encounter in his oeuvre.

The 1828 & 1913 Webster that is available online does not include the obsolete “delire”, but the OED does, not the digital version but the hefty tomes I have in my library.

Delire. v. Obs. To be delirious or mad, to rave.

In this sense, the first and last instances cited by the OED are from the 17^th century; the latter is dated 1675 from R. Burthogge’s Causa Dei, 196:

               He delires, and is out of his Wits, that would preferr it [moonlight] before the Sun by Day.
