Extracts of Terminology Lexicons Types in Level of Concept Expression

Abstract

It can be emphasized that depending on the types of human activities, whether is that common, simple or high, the types of lexical language units function, moving from one conceptual level to the other according to the need of the communication necessities presented in front of the language. It can be noticed clearly, not rarely, in technical communication, as in other communications, and particularly in this case, the same sign as a lexical unit that expresses a common concept of wide content can also indicate a concept of a special content , restricted to its use and known by a narrow circle of users of the language, as it can be said for foot (man) and foot (mineral), pocket (coat) and pocket (petroleum), horn (animal) and horn (anvil). In this case, with the highest level in which the word rises, a modified concept of a lower or higher degree is also associated comparing with the meaning of the unit it’s coming from, for example, pocket (higher), compared to pocket (coat) (lower). In another case, raising the word to a higher level can only be considered as a transition to another level, but more or less of the same conceptual content. This type of concept, which is also called a dual concept (Duro, 1983: 113), makes the same unit to elevate to the highest level, in addition to the concept that expresses as: door1 (common word) and door1.1 . (building), window1 (house) and window1.1. (buildings), as a special common unit and of construction field.
