Final answer:
The process of aphesis involves the elimination of an unaccented vowel at the beginning of a word and is true. This phenomenon demonstrates how words can change over time. Another related word alteration involves rules for deleting a final 'e' when adding suffixes, depending on the following letter.
Step-by-step explanation:
The statement that aphesis is the process whereby an unaccented vowel at the beginning of a word often falls off is true. Aphesis is a linguistic phenomenon where initial unstressed vowels become elided over time, especially in the development of English. For example, the word 'around' has evolved from the Middle English word 'aronde', demonstrating aphesis.
Another linguistic process related to the alteration of word forms is the deletion of a final e. When adding a suffix, there are specific rules about when to keep or delete the final e. Generally, you only delete the final e that marks a soft c when you add a suffix that starts with e, i, or y, or you delete it if it is only marking a long vowel whenever you add a suffix that starts with any vowel. This is important in understanding the correct spelling of words after suffixation, as in the example 'notice' becomes 'noticeable', where the final e is kept to maintain the soft c sound.
