3.The architecture of a dictionary


1.What are the megastructure and the macrostructure of a lexicon?Give examples.

The Megastructure af a dictionary is the general structure of a dictionary,which includes the front matter,list of abbreviations,grammar explanations,the metadata,body of the dictionary(which is the macrostructure)and the back matter.

The Macrostructure deals with the organisation of the lexical entries at the level of body of a dictionary,weather is organised as a list ,network or it has tree structure.

2.What is semasiological and onomasiological dictionary?

A semasiological dictionary is a decoding dictionary .called also reader´s dictionary.It´s macrostructure is a list,and includes mainly standard definitions(by nearest kind and specific differences)

An onomasiological dictionary is an encoding dictionary,also called writer´s dictionary,because the meaning of a lexical entry is not given with an explanation,but through synonyms.It has tree structure.It is a Thesaurus.

3.What is the microstructure of a dictionary?

The Microstructure is the organisation of information within the lexical entries.

4.What kind of lexical information is contained in a dictionary´s microstructure?

The microstructure gives information about the meaning of the lexical entry,orthography,pronunciation(IPA transcription),word formation,POS.

5.What is mesostructure?

The mesostructure of a dictionary include relations between lexical entries and other entities.

6.Give examples of mesostructural elements concerning:

a)types of info with reference to the sign model:modality,grammar,object semantics

b)linguistic description reference:abbreviations for parts of speech,characterisation of spelling.

c)cross-references between related entries:co-hyponyms

d)corpus -references:concordance.
