Main types of English dictionaries.

ENCYCLOPAEDIC AND LINGUISTIC DICTIONARIES. The choice of words: thing-books vs wordbooks;
all words of the language vs words of designative character (names for substances, diseases, animals,
institutions, terms of science, biographical data). The information about a word in an entry: spelling,
pronunciation, meaning, examples of use vs extensive extralinguistic information. Cf the entries for CAT:
CAT (family Felidae), any of a group of carnivorous mammals that includes the true cats—lion, tiger,
jaguar, leopard, puma, and domestic cat—and the cheetah (see photograph).
