【正确答案】正确答案：The origin of the field theory of semantics is the lexical field theory introduced by Jost Trier in the 1930s. Semantic field is a term referring to the phenomenon that vocabulary is an integrated system interrelated in sense and can be divided into semantically related sets or fields. Words in each semantic field define one another, so a meaning of a word is dependent partly on its relation to other words in the same conceptual area. Semantic field is concerned with the vocabulary of a language as a system of interrelated lexical networks.
