Did You Know?

The handy Latin prefix ob-, meaning "in the way," "against," or "toward," occurs in many Latin and English words. "Obstreperous" comes from ob- plus strepere, a verb meaning "to make a noise," so someone who is obstreperous is literally making noise to rebel against something, much like a protesting crowd or an unruly child. The word has been used in English since around the beginning of the 17th century. "Strepere" has not played a role in the formation of any other notable English words, but "ob-" words abound; these include "obese," "obnoxious," "occasion," "offend," "omit," "oppress," and "oust."
