Terminology

Terminology is the study of terms and their use. Terms are words and compound words that in specific contexts are given specific meanings, meanings that may deviate from the meaning the same words have in other contexts and in everyday language. The discipline Terminology studies among other things how such terms of art come to be and their interrelationships within a culture. Terminology differs from lexicography in studying concepts, conceptual systems, and their labels ( terms), whereas lexicography study words and their meanings.

Terminology thus denotes a discipline which systematically studies the labelling or designating of concepts particular to one or more subject fields or domains of human activity, through research and analysis of terms in context, for the purpose of documenting and promoting consistent usage. This study can be limited to one language or can cover more than one language at the same time ( multilingual terminology, bilingual terminology, and so forth) or may focus on studies of terms across fields.
