 Hi, this unit discusses the basic concepts of phonology, the subdivision of phonology into segmental and suprasegmental phonology and practical aspects of phonology such as the phonemic transcription of English. The content with its question set in the How to Proceed section as default guidance discusses the relationship between phonetics and phonology and we will investigate the principles governing segmental as well as suprasegmental phonology. Furthermore, we will look at a practical aspect of phonological studies namely the use of phonetic transcription systems. Don't forget to document your learning progress by ticking off each activity you have mastered. The mastery test involves an input task where you have to identify the number of phonemes, vowels or consonants within a word. We suggest that before you actually type in your solution write down the word on a piece of paper for close inspection first. The suggestions for in-class activities confront you with data from several languages and want you to define the phonemes within the data. Difficult but with the main content in mind manageable. So make use of all these options to get an idea of the basics of phonology.
