Adjective Suffixes

In Unit 1 in our textbook we had a look at adjective suffixes. A suffix is a particle that is added to a word to form a new word with a different meaning or function. Here are some suffixes that are commonly added to nouns in order to form adjectives.

If you  add -ly to an adjective, you'll create an adverb:

• Calm - calmly
• Beautiful - beautifully
• Logical - logically

"The Logical Song", by Supertramp, features a good number of adjectives and adverbs created with these suffixes.
