Did You Know?

"Hypothecate" is a controversial word. It has existed as a synonym of "hypothesize" since 1906, showing up primarily in scientific and linguistic sources, but usage commentators have long criticized it, from Henry Fowler in 1926 to Harry Shaw in 1987. It is sometimes perceived as a mistaken use of another "hypothecate," one meaning "to pledge as security without title or possession." Both "hypothecate" homographs -- and "hypothesize" too -- derive ultimately from the Greek "hypotithenai" ("to put under," "to suppose," or "to deposit as a pledge"), but each entered English by a different route. The hypothesizing "hypothecate" is a legitimate (albeit uncommon) word in its own right, not a misuse of its homograph. If you want to avoid the controversy altogether, however, you can stick with the more common "hypothesize."
