Terminology refers to a specialized set of technical words and expressions used in a particular field of knowledge, profession, science, technology, law, medicine, commerce, administration, or any specialized discipline. These terms have precise, fixed, and context-specific meanings, unlike ordinary vocabulary, which may have multiple meanings depending on usage. In lexicography, terminology plays a significant role because it ensures clarity, uniformity, accuracy, and effective communication among experts, translators, teachers, students, and general users. In translation, the correct use of terminology is essential for preserving the intended meaning of the source text and avoiding ambiguity. The development of terminological vocabulary is a systematic process guided by linguistic principles, subject knowledge, and practical requirements. One of the most important techniques is translation or equivalence, in which an appropriate equivalent term is created in the target language. For example, the English word *Constitution* is translated as *Samvidhan*, *Democracy* as *Loktantra*, and *Environment* as *Paryavaran*. Such equivalents preserve both meaning and functional value. Another important technique is transliteration, where the pronunciation of the original word is retained by writing it in the script of the target language. This method is generally adopted when no suitable equivalent exists or when the borrowed term has gained widespread acceptance. Examples include *Computer (Kampyutar)*, *Internet*, *Laser*, and *Radar*. These words have become common in Hindi without significant semantic change. Borrowing or adoption is another widely used technique. In
