However, it can be part of a compound adjective when combined with other words, such as:
* Sale price: The price at which something is sold during a sale.
* Sale item: An item that is being offered at a discounted price during a sale.
* Sale day: A day dedicated to selling items at discounted prices.
So, while "sale" isn't an adjective by itself, it can be used to form compound adjectives that describe something related to a sale.
