Final answer:
The ending rules in question are the VCle and VCCle syllable patterns and the Final 'e' Deletion Rule for suffixes. The VCle pattern usually has a long vowel, while the VCCle pattern generally has a short vowel. The Final 'e' Deletion Rule applies to words ending in 'e' when suffixes starting with 'e', 'i', or 'y' are added.
Step-by-step explanation:
The rules used here are based on syllable patterns in English spelling, particularly involving the endings of words. Based on the provided information, the pattern we're looking at is where a single vowel is followed by one consonant and an le (VCle) or a vowel followed by two consonants and an le (VCCle).
In words with the VCle pattern such as char and ally, the ending silent 'e' often makes the preceding vowel long. For example, in the word noble, the 'o' is long because it follows the VCle pattern. Conversely, in the VCCle pattern, the vowel is often short, as seen in the word rifle, where the 'i' is short.
The Final e Deletion Rule comes into play when adding suffixes. If a word ends in a silent 'e', that 'e' is typically dropped when adding a suffix that begins with e, i, or y, especially if it follows a soft 'c' or 'g'. An example is changing the word shape to shapely, where the 'e' is dropped in the suffix 'ly'.
