Final answer:
The suffix appears only at the end of a word, such as "-ion" in "digestion" and "-er" in "questioner". It can alter the word's meaning or grammatical function, and there are specific spelling rules, like the Final (e) Deletion Rule and Twinning or Doubling Rule, that apply when adding suffixes.
Step-by-step explanation:
The suffix is a word element that D. will only appear at the end of the word. A suffix is a set of letters added to the end of a word to change its meaning or grammatical function. Examples include the "-ion" in "digestion", the "-er" in "questioner", the "-ous" in "adventurous", the "-al" in "scriptural", and the "-ure" in "literature". All these examples show the suffixes are added to the base or stem to form new words.
In cases of spelling rules for suffixes, certain patterns such as the Final (e) Deletion Rule dictate that a silent 'e' at the end of the base is often dropped before adding a suffix beginning with a vowel, as in "gallery + ies". Another pattern is that a consonant may be doubled under certain conditions, as in the Twinning or Doubling Rule.
