tropic
When referring to the specific lines of latitude, the word is typically used as a proper noun in phrases like the Tropic of Cancer. In this sense, it denotes a precise astronomical boundary.
Users should distinguish between the noun tropic and the more common adjective tropical. While tropic can be used as an adjective to describe characteristics of these regions, tropical is the standard choice for most descriptive contexts, such as tropical storms or tropical fruit.
