Semantics: SUDDENLY

[Dan Parvaz]

According to work done by James Macfarlane (Jim -- you out there?), as WRONG grammaticized into SUDDENLY (aka a marker of mirativity), one of the stops along the way was "unexpected and undesirable." It would make sense for that earlier sense to still be in use. The simplified cline (Macfarlane obviously includes more detail) is as follows:

Incorrect ----> unexpected and undesirable -----> unexpected
