Types of chunks :
The Lexical
Approach consists of three main types of chunks:
· Collocations: words of the four
main parts of speech which go together, usually, but not always, two words.
· Fixed expressions : expressions
which cannot be changed or can only be changed minimally. Most fixed
expressions are idiomatic or are those used in polite speech (e.g., How's it
going?).
· Semi-fixed expressions: expressions
which have at least one slot into which a number of different words or phrases
can be inserted.
