Question 1: What is meant by the broad definition of morphology?
The broad definition of morphology means the study of how words are formed and how smaller meaningful units called morphemes are combined to create new words and meanings, and this definition does not focus only on grammatical endings but also includes all processes of word formation, and according to the Morphology course book in the attached file, morphology in the broader sense mainly deals with derivational morphology, compounding, and conversion rather than only inflectional morphology, because derivation creates new words such as when the verb teach becomes the noun teacher by adding the suffix -er which changes both meaning and word class, and compounding happens when two seperate words like hand and book are joined together to form handbook which has a new meaning different from the original words, and conversion also plays an important role in the broad definition since words like put can function as present or past depending on context without any change in form, and this idea is also clearly explained by Andrew Carstairs-McCarthy in his book An Introduction to English Morphology, where he states that morphology is not limited to grammatical variation but also explains how vocabualry expands in a language, and both the course book and Carstairs-McCarthy explain that words are complex units made up of morphemes such as play, player, and replay where each added morpheme changes the meaning or function of the word, and morphology in the broad sense also studies the difference between content words and function words, since content words like nouns, verbs, adjectives, and adverbs are open classes that allow the addition of new words, while function words such as articles and prepositions are closed classes, and the book also explains morphological parsing where words are analysed into roots and grammatical markers like cats being analysed as cat plus plural marker, and this helps learners understand how words are structured internally, therefore the broad definition of morphology connects word structure, word meaning, and word formation processes, and it helps explain how language grows, develops, and allows speakers to create and understand new words in a systematic way rather than randomly.
