What is the difference?
The major contrast between "quite" and "quiet" is in regard to significance and application.
"Quite" is one of the adverbs that is used to stress the manner or degree of doing something up to the measure. It turns on adjectives and other words to intensify their meaning or indicate that they are complete.
Meanwhile, 'quiet' is a noun or an adjective that is used to refer to a state or condition that lacks sound or is calm. "Quite" is used with reference to the level of a particular feature, while "quiet" has to do with noise and calmness.
