For the most part no, but some do. Here is an example: change-changing.
Sometimes yes, the spelling of the original word may change when adding a suffix, particularly if the word ends in a silent 'e' or a consonant preceded by a single vowel. In such cases, the final 'e' may be dropped or the final consonant may be doubled before adding the suffix.
Yes, these are called "prefix-bound" or "suffix-bound" words. They are words that alter their pronunciation when combined with a prefix or suffix.
a suffix will change the meaning
A suffix
The suffix is -ty. "Animus" is the original Latin root, meaning "spirit" and the -ty is the suffix (which creates a noun denoting a condition) -- thus the new word, "animosity." It is similar to the words bellicosity (from "bellus") and verbosity (from "verbum").
Words that are suffix-less are called root words.
When suffixes are added to words, it can change the meaning, part of speech, or tense of the original word. For example, adding "-ed" to "cook" changes it from a verb to a past tense verb ("cooked"). Suffixes can also create new words or modify the original word's grammatical function.
Words do not begin with a suffix. A suffix come at the end of a word.
