The study of sign processes, which include any activity, conduct or process that involves signs, is called semiotics. A sign is defined as anything that communicates a meaning to the interpreter, other than the sign itself. Signs can be communicated through any of the senses. This includes visual, auditory, tactile, olfactory or gustatory senses. In the study of semiotics, signs and symbols are considered to be a significant part of communications. Unlike linguistics, it also studies non-linguistic sign systems. Signs and sign processes, indication, designation, likeness, analogy, allegory, metonymy, metaphor, symbolism, signification and communication are all studied in this field. Some of its major subfields are syntactics, cognitive semiotics, finite semiotics and pictorial semiotics. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in semiotics. It provides comprehensive insights into this field. Researchers and students in this field will be assisted by this book.
