Word Errors: jury-rigged, jerry-built

The most common screwup on these terms is mixing them: 'jerry-rigged' or sometimes 'jury-built'. I saw 'jerry-rigged' recently in The New Yorker and in an interview in the literary magazine, The Sun.

Jury-rigged means temporarily repaired with materials not intended for their new use. Break the mast of your small sailboat, and you could jury-rig a mast with an oar.

Jerry-built means slapped together with materials at hand, or poorly constructed from substandard materials.
