Whet Your Appetite – Meaning, Origin and Usage

Did walking by that wonderful restaurant make your stomach growl? Has a book you’re reading made you want to learn more about something? In both cases, the idiom “whet your appetite” can describe what you’re feeling. Keep reading to discover the meaning and origins of this commonly-used, but little-understood, phrase.


The idiom “to whet your appetite” essentially means “to become more interested in something“.

As the often misunderstood “whet” comes from the whetstone that is used to sharpen knives, the idiom could be translated to modern English as “to sharpen your appetite“.

The appetite in question can refer to food, of course, but also to anything else. Encountering a little of something can stimulate your interest in more.

​​Example Usage

Are you curious how the phrase “whet your appetite” can be used in practice? Take a look at these examples to see just how versatile the idiom is:

The first use of the idiom “to whet your appetite” was recorded in the seventeenth century, and the appetite in question has always referred to both food and anything else someone might be “hungry” for — including knowledge and entertainment.

Because the idiom is commonly misspelled as “wet your appetite”, it can be helpful to understand where “whet” came from. This word came from the Old English “hwettan”, which meant “to sharpen” (knives and tools) as well as “to incite”.

The word “appetite”, meanwhile, comes from French, and initially referred to desire or longing in general. The word is now mostly, but not exclusively, associated with a desire for food.

Combining these two concepts, it becomes clear that the saying “to whet your appetite” means to sharpen or polish one’s desire.
