Human Behavior Recognition

This chapter foregrounds vocabulary as central to meaning making in discourse and highlights that the three aspects of vocabulary, viz., form, meaning, and use, are not separate but interconnected. Rather than showing vocabulary as a static list of words, it presents it as a dynamic carrier of conceptual, cultural, and contextual knowledge. It explores how roots, prefixes, and suffixes form the internal structure of words, thereby contributing to meaning and grammatical function. It also illustrates how historical factors shape word pronunciation and spelling. This chapter treats meaning not as fixed but as encyclopaedic, context-dependent, and experience-based, with polysemy and metaphorical extension playing a crucial role. Further, with the help of word webs, it highlights how vocabulary is mentally organised through associations. In addition, this chapter examines vocabulary in use, focusing on how word choice is determined by social and pragmatic factors, such as situation, tone, formality, register, and collocation. Finally, it describes vocabulary learning as a gradual process and underscores the importance of exposure, context, and practice in vocabulary development.
