Final answer:
The suffix indicating 'new opening' related to the mouth is not directly provided in the exercises. The exercises involve combining prefixes, bases, and suffixes, with a focus on palatalization, to form new words. Examples include 'digestion' with palatalized [ch] and 'galleries' where 'i' represents the sound [ē].
Step-by-step explanation:
The student has asked for the identification of a suffix based on its meaning which signifies a 'new opening (to form a mouth).' In the context of the provided instructions, the relevant suffix is not explicitly given. However, the concept appears to relate to medical terminology, such as '-stomy' (a suffix used in medicine indicating the creation of an opening), but this does not tie directly to the exercise provided.
For the exercise given, combining prefixes, bases, and suffixes with examples could produce the following words with palatalization, indicated by the sound [ch], spelled as :
- disgestion - The combination of 'dis + gest + ion' where the 't' in 'gest' represents the [ch] sound after palatalization.
- spiritual - The word 'spirit + ual' does not specifically show palatalization and is provided as an example.
- questioner - Here, 'question + er' includes the 't' representing [ch] sound.
- And so on for the rest of the examples.
The act of creating new words by adding suffixes or altering the base can change pronunciation and meaning. In the case of 'gallery + i + es', the resulting word is 'galleries' where the 'i' represents the sound [ē]. Similar changes apply to 'hurry + i + es' forming 'hurries' and other examples provided.
In summary, the question prompts an examination of how suffixes and stems combined to produce new words within the rules of English morphology and phonology.
