Morphology is the study of words, how they are formed, and their relation to other words in the same language. It analyzes the structure and parts of words, such as stems, root words, prefixes and suffixes. Morphology also covers parts of speech, intonation and stress, and the ways in which context can change the pronunciation and meaning of a word. While words and clitics are generally accepted as the smallest units of syntax, many words can be related to other words in most languages by rules that collectively describe its grammar. Lexeme is a theoretical entity which conveys the shared syntactic properties of a group of word forms and their unitary meaning. The aim of this book is to present researches that have transformed the study of lexemes and aided its advancement. It explores all the important aspects of morphology in the present day scenario. This book will help new researchers by foregrounding their knowledge in this branch.
