Final answer:
The question falls under an English phonology exercise focused on the analysis of sound pronunciation and orthography in language, likely aimed at college students in Speech-Language Pathology or similar studies.
Step-by-step explanation:
The question indicates a process of phonological analysis, most likely in the context of a Speech-Language Pathology program or a similar subject where the articulation of sounds is studied. In these exercises, words containing specific sounds like /f/, /z/, and /sh/ are analyzed to see if the target sounds are being replaced. The practice of sorting words into sound categories and the analysis of whether a final is added or deleted are necessary to understand how sounds and letters interact in language construction.
For example, when analyzing a word like 'announce', and with the addition of '-er', we document whether the final in 'announce' is deleted in the derived form 'announcer'. We would then write 'Yes' in the column if the was deleted, or 'No' if it was retained. The same process applies to the analysis of words for the presence of the sounds [sh], [ch], and others, as well as their spelling representations.
The question seems to be part of a phonetics or phonology assignment designed to understand the subtleties in sound pronunciation and how they are influenced by adjacent letters and word structures. The activity is important not just for linguistic analysis but also for language teaching, speech therapy, and similar areas that deal with speech and pronunciation.
