When we think of words, we often only think of a single meaning. But words can have many meanings and applications. Not surprisingly, even the term “lexicology” has a number of different meanings, depending on which dictionary you consult. The Concise Oxford English Dictionary (OED), 10th edition, defines it as “the study of the form, meaning, and behavior of words”;1 Merriam-Webster’s Collegiate Dictionary, 11th edition, defines it as “a branch of linguistics concerned with the signification and application of words”;2 and the American Heritage College Dictionary, 4th edition, similarly defines it as “[t]he branch of linguistics that deals with the lexical component of language.”3 Depending on the particular application of the word “lexicology,” one definition may not be a perfect substitute for another. In other words, these definitions could be said to be ambiguous.
