Explanation:
All the words above have one thing in common: they are all formed with suffixes. Suffixes are affixes placed at the ending of a word with the purpose of modifying it, forming a new word. Different suffixes convey different meanings. For instance, the suffix -able means "capable of being or doing something", while the suffix -ous forms adjectives that indicate the possession of a quality. When we know suffixes, we are able to infer the meaning of words that have them.
