1） Monolingual dictionaries vs.bilingual dictionaries
Monolingual dictionaries are written in one language, while bilingual dictionaries are written in two languages.Bilingual dictionaries are of the two types". One is that the entries are defined and explained in the same language with translations.The other is that the entries are defined in one language and given their foreign equivalents.
2）Linguistic and encyclopedic dictionaries
Linguistic dictionaries aim at providing linguistic information about the head words, such as pronounciation, spelling, meaning, part of speech, etc……
Encyclopedic dictionaries are of the two kinds:one is encyclopedia, which aims at providing encylopedic information about the headwords. The other is encyclopedic dictionary, which shares the characteristics of both a linguistic dictionary and an encyclopedia.
