 Welcome! This unit introduces the basic concepts of phonology and points out the differences between phonology and phonetics. In the virtual session where, as usual, you can use the question sheet as a default guide through the unit, we will discuss the relationship between phonetics and phonology, we will look at the distinction between segmental and suprasegmental phonology and we will discuss some selected phonological phenomena. The mastery worksheet is a listening task where you have to identify the number of phonemes within a given English word. With some practicing you shouldn't encounter too many problems. The practical uses individual sound segments to discuss their relevance for particular sound systems and provides you with data to perform some simple phonological analyses. In summary, quite complex but manageable.
