How to Find Common Words in a Text

Abstract

The process of finding common words in a text is one of the fundamental tasks in corpus linguistics and computational language analysis. Identifying frequently occurring words helps researchers understand the lexical profile of a text, determine its key topics, and compare it with other texts or registers. This paper discusses practical methods for finding common words using both manual and computational approaches, explains their significance for linguistic research, and highlights applications in teaching, stylistics, and lexicography.
