Reference Book
A dictionary is a reference book that lists words in a language and provides the meaning, origin and pronunciation of each listed word. The book also informs users on how to use a word in different circumstances.
Semasiological, of Course
Dictionaries are semasiological. Semasiology is the branch of linguistics that deals with the definition of words and phrases in a language. This is different from onomasiology, which deals with what things and concepts are called. A thesuarus is an onomasiological reference book because it provides users the different terms that can be used to express a specific idea.
