Adding prefixes and suffixes to words is a common way to create new words in English. Let's explore how we can do this with the words provided:
Fiction : Adding 'non-' as a prefix gives us "nonfiction" , which means writing that is based on real events and facts. Adding '-al' as a suffix gives us "fictional" , meaning something invented by the imagination.
Visible : By adding the prefix 'in-', we get "invisible" , which refers to something that cannot be seen. Adding the suffix '-ity' gives us "visibility" , meaning the state of being able to see or be seen.
Teach : Adding the suffix '-er' forms "teacher" , which is a person who teaches. Adding '-ing' creates "teaching" , which refers to the act or profession of educating others.
Do : By adding '-able' as a suffix, we form "doable" , meaning something that can be done. Adding '-er' gives us "doer" , which refers to a person who performs an action.
Poet : Adding the suffix '-ry' gives us "poetry" , which is the art or work of a poet. Adding '-ess' can form "poetess" , which is an old-fashioned term for a female poet.
In each case, the prefix or suffix modifies the base word to create a new meaning or part of speech. Prefixes are added to the beginning of a word, while suffixes are added to the end.
