Definition: A letter or a group of letters attached to the beginning of a word that partly indicates its meaning. Common prefixes include anti- (against), co- (with), mis- (wrong, bad), and trans- (across). See also: Common Prefixes. From the Latin, "to fasten in front"
* circum = around
"Some circumstantial evidence is very strong, as when you find a trout in the milk."
(Henry David Thoreau) *
* dis = apart, away
"Finance is the art of passing money from hand to hand until it finally disappears."
(Robert W. Sarnoff) *
* pre = before
"What does it mean to pre-board? Do you get on [a plane] before you get on?"
(George Carlin) *
* "We're talking prefixes today. By my inaccurate and utterly unreliable count, contemporary lexicographers list 152 'dis' words and 161 'mis' words. The 'dis' list begins with the verb 'to dis' (or diss), meaning 'to treat with contempt or disrespect." It ends with 'disvalue,' i.e., to depreciate, consider of little value. The 'mis' list begins with 'misact,' which no one has ever seen in print or heard in speech. It runs on to 'misuse,' which happens to writers every day."
(James Kilpatrick, "To 'dis,' or not to 'dis,'" June 4, 2007) *
* "If lawyers are disbarred and clergymen defrocked, doesn't it follow that electricians can be delighted, musicians denoted?"
(George Carlin) *
* "Lately the prefix trend has been shrinking. During the 1980s, 'mini-' gave way to 'micro-,' which has yielded to 'nano-.' In the new millennium, companies such as Nanometrics, Nanogen and NanoPierce Technologies have all embraced the prefix, despite complaints their products were hardly nano-scale (a billionth of a meter or smaller). Even Eddie Bauer sells stain-resistant nano-pants. (They're available in 'extra-large' for the retailer's not-so-nano customers.)"
