On Thursday, Merriam-Webster announced its latest update, including googling as part of its lexicon of new science and technology words. Along with googling, also added to the venerable dictionary's lexicon are terms such as agritourism, biodiesel, mouse potato, ringtone and spyware.

The new words from Merriam-Webster are already available online and will be included in the 2006 print version of Merriam-Webster's Collegiate Dictionary, (Eleventh Edition) due out this fall.

It is only recently, observers point out, that many regularly used technical words are getting the official stamp of approval from English-language dictionaries. The earliest known use of the word technology was not until 1859.

To celebrate the 200th anniversary of Noah Webster's A Compendious Dictionary of the English Language, the Merriam-Webster Web site is featuring a glossary highlighting Webster's original entries. These are words that were commonly used in America but were not yet found in any English language dictionary.

Some of Webster's science and mathematics terms included: aeriform, caloric, decahedron, electrician, galvanism, ignescent, vaccine and vaporize.
