Have you been guilty of catachresis* at work? Have you defenestrated* your dictionary in frustration? Do you have phloem bundles* stuck in your diastema*? Scratching your occiput* now?

Rod L. Evans's Thingamajigs and Whatchamacallits will help take the mystery out of some of our most obscure words. Containing hundreds of words from agitron (the phenomenon of wiggly lines in comic strips indicating that something is shaking) to zarf (the holder for a paper cone coffee cup), this lively reference will enable you to easily locate your thingamajig or whatchamacallit, be it animal, vegetable, mineral, or punctuation mark.

Leave no linguistic oddity unexamined—your brain will thank you.
