The Word of the Day for October 28 is:

Example sentence:

14, 2001)

Did you know?
     You're probably familiar with "adjacent," and if you 
guessed that it's a relative of "superjacent," you're right. 
Both derive from the Latin verb "jacere," meaning "to 
lie." "Adjacent," which is both the more popular and the earlier 
word (it first appeared in print in the 15th century, 
while "superjacent" turned up in 1610), comes from "jacere" and 
the prefix "ad-," meaning "near." "Superjacent," on the other 
hand, was formed by combining "jacere" with the prefix "super-," 
meaning "over," "above," or "on top of." In case you were 
wondering, "jacere" descendants are also available for other 
possible configurations -- "subjacent" means "lying below," 
and "circumjacent" means "lying near on all sides" 
or "surrounding."
