They sang quite loudly. (Quite modifies "loudly", an adverb)


Suffixes - letters or syllables that are added at the end of a root word.  A suffix can change the grammatical function or use of the root word.  It can also change the word's meaning.

Learning the function and meaning of some of the most commonly used suffixes can increase your vocabulary.

Some suffixes change the grammatical structure of a root word, but do not change the basic meaning of the word.  For example, some suffixes are used only to change the tense of a verb, not its meaning.

 Present Tense  Participle  Past Tense
 work  working  worked



Some suffixes are used to make a verb agree with its subject in person, without changing the meaning of the word

 I sing  He sings

Other suffixes change words from singular to plural.  LIke the suffixes mentioned in the above example, these suffixes do not change the meaning of the word.

 one coat  many coats


Suffixes can not only change the meaning of the root word, but it can also change how the word is used in a sentence.

Look at how noun-forming suffixes can change the meaning of the root word "experiment:.

 experimenter - a person

 experimentalist - a person

 experimentation - a process

 experimentalism - a belief
