20. Some basic problems of dictionary compiling.
Problems:
1) Selections of words
nature(whether to include scientific, technical terms,
Shakespeare’s lg, slang, neologisms etc)
number(the biggest is of 600,000 words)
According to frequency of usage.
2) Arrangement of the entries:
- spelling
- pronunciation
- grammatical inform.
- definition (encyclopedic, synonyms, translation)
(in unilingual dictionary-to give the synonyms or to give encyclopedic definition)
Ways of arranging:
alphabetical
thematically
nests/clusters
3) Are derivatives worth separate entries; Where to put prepositions
4) From where to take the examples; do we need them at all?
