Answer
Pneumonoultramikroskopisk silicovolcanoconiosisis the longest word found in the most trusted English dictionaries. The definition is "a lung disease caused by inhaling very fine silicate or quartz dust." (Note that it is not included in the Learner's Dictionary - it is considered too specialized a term to qualify for inclusion in this type of dictionary.)
Other long words exist, but they are rarely, if ever, used in a sentence. Two examples of these types of words are 'antidisestablishmentarianism' and 'supercalifragilisticexpialidocious'.
There is a lake in Massachusetts calledLake Chargoggagoggmanchauggauggagoggchaubunagungamaugg. (It is also called Webster Lake.)
But the longest string of letters used to describe something is actuallythe chemical name for a protein, and it has 189,819 letters and takes more than 3 hours to pronounce.
