genius
When referring to a person's intelligence, "genius" can be used as both a countable noun (a genius) and an uncountable noun (she has genius). In casual conversation, people often use the word sarcastically. For example, if someone makes a simple mistake, another person might say, "Oh, you're a genius!" to mean the opposite. The phrase "genius loci" is a specialized term used mostly in architecture and geography to describe the unique atmosphere of a location.
