Thematic groups

Thematic classification is based on the co-occurrence of words in certain repeatedly used contexts onthe level of the sentence. Words are joined together by common contextual associations within the framework of the sentence reflect the link of things and events. Words making up a thematic group belong to different parts of speech. The exemple of well-known thematic subgroups are terms of kinship, names for the parts of the human body, colour term, military terms, names of animals, birds, plants, heavenly bodies, and so on.

2. Semantic classification of words,

By the term "semantic field" (conceptual field) we understand-sectors of vocabulary which compri^{se words}characterized by a common concept as the common denominator of their meaning. For example, the words ertj°^^men ^s' happiness. Joy, belong to the semantic field of emotions; blue, yellow, green, red ~ to the semantic field of со\°^т⁵' members of the semantic field are not synonyms. But all of them are joined together by some common ^seman ^1Ccomponent which is common to all members of the field and described as common denominator of me^¹¹¹¹^ m'.;nbers of the semantic field are semantically independent because each member helps to delimit the mean'¹¹*' ° ^l ^sneighbours and semantically determined by them.

Small lexical groups consisting of words of the same part of speech are usually defined as lexico'^seman ^ICgroups. The reason for joining words together into semantic field and lexico-semantic groups is the identity of O^iie ° ^ecomponents of their meaning found in all lexical units forming these lexical groups. For instance, the word sale^"^wornanmay be included into different lexico-semantic groups such as profession, female, human. Different rae^¹¹¹"^ ° polysemantic words make it possible to refer the same word to different lexico-semantic groups.

З. Hyponymic relations.

Another approach to classification of the vocabulary is the study of hyponymic relations. By hyponymya semantic relationship of inclusion. For example, vehicle may include car, bus, taxy, etc. The hyponymic relations may be studied as hierarchical relationship between the meaning of the general and the individual terms.
