quite
To mean fairly or completely, depending on how it is used.
Quite is a word that makes other words stronger or softer, depending on how you use it.
In American English, when people say something is quite good, they often mean it's pretty good but not amazing. “The movie was quite interesting” suggests it held your attention without being spectacular. In this way, quite can soften the word it modifies, like turning down the volume just a bit.
In British English, quite can work differently. Sometimes it softens a word, and sometimes it strengthens it. For example, “quite brilliant” can mean very brilliant, and “quite impossible” means completely impossible. In these cases, quite turns the volume up instead of down.
The word can also mean completely or entirely, especially in phrases like quite sure, quite right, or quite finished. When your teacher asks if you're quite certain you checked your work, she means totally certain, not somewhat certain.
This double meaning sometimes creates confusion. If someone says a book is “quite good,” you might wonder: do they mean fairly good or really good? Context and tone usually make it clear. In American English, you're often safer assuming quite means “fairly” or “rather.” If someone means “completely,” they'll often add emphasis: “I'm quite certain!” or “That's quite enough!”
