Abstract Vocabulary is the main building block of language use and language learning. Every phrase of any length consists of words and without words no verbal communication is possible. However, the number of words in any language is a great one. Even the native speakers of any language do not know the meaning of all the words in their language. However, according to Register Analysis, language varies from context to context and different registers use certain words and structures more frequently than others. Therefore, materials developers in ESP (English for Specific Purposes) should distinguish the most important vocabularies within their subjectspecific areas and focus on them when preparing materials and textbooks for their students. One of the main criteria for distinguishing the important words is their frequency of occurrence. The present study attempts to work out the most frequent, thus most important, words of EST (English for Science and Technology) which is a branch of ESP.
