Name
Suffixes are word parts added to the ends of base words to
change their meanings or their parts of speech.
• The suffix -ity means “the state of.” For example, when you add
the suffix -ity to visible, the word visibility means “the state of
being visible.”
• The suffix -ion means “act or process.” When you add -ion
to demonstrate, the word demonstration means “the act of
demonstrating.”
• The suffix -ous means “having the qualities of.” For example,
when you add -ous to the word poison, the word poisonous
means “having the qualities of poison.”
