sockdolager

The verb sock ("to punch") and the noun doxology ("a hymn of praise to God") may seem like an odd pairing, but it is a match that has been promoted by a few word mavens when discussing the origins of the Americanism sockdolager. Don't be too quick to believe the hype, however. When a word's origin is simply unknown, as is the case with sockdolager, there's a tendency for folks to fill in the gap with an interesting story, whether or not it can be verified. In the case of sockdolager, the "sock" part is plausible but unproven, and the "doxology" to dolager suggestion is highly questionable. The theory continues to have many fans, but it can't deliver the knockout punch.
