　　“Look it up in the dictionary” is the usual comment when people are in
doubt about the meaning or spelling of a word.Dictionaries are considered the
final authority on these matters as well as on pronunciations and other facts
about a word.
　　Until a few hundred years ago,however,people could not “look it up”
because there were no English dictionaries.The ancient Greeks and Romans and
the scholars of the Middle Ages had made lists of Latin and Greek words.

speech,grammatical forms,and ways of use.The smaller ones do not provide all
this information.
