Don’t Look a Gift Horse In The Mouth


If someone says “don’t look a gift horse in the mouth,” it means that when you receive a gift, do not be ungrateful.

Example: Kyle was gifted a fancy watch by his brother. However, instead of being grateful, he started examining it for flaws. He also checked to see if the brand and color were to his liking. Later, Kyle said to his friend, “I’m not sure I want to wear this watch; it looks cheap. What should I do?” So his friend advised, “As the saying goes, don’t look a gift horse in the mouth.”

(In other words, instead of being unthankful, he should appreciate the gift.)

The Origin Of – Don’t Look a Gift Horse In The Mouth

What is the origin of this common saying? Unfortunately, it is not clear how the proverb “don’t look a gift horse in the mouth” originated, but we can speculate. If we look at the phrase, it sounds like it came from a time or place where receiving a horse as a gift was a regular occurrence. After receiving this gift, people would literally look into the horse’s mouth, which was considered rude. Why so?

The reason people would look a gift horse in the mouth is to determine its age. Yes, a horse’s age can be deduced by inspecting its teeth. The longer the teeth, the older the horse. Thus, looking a gift horse in the mouth would be considered rude because the person is essentially examining the horse to see how old it is. Maybe its old enough that they don’t even want it. But the horse was a gift, so should they really be so picky?

While we can mostly just speculate about the origin of this phrase, it’s possible that the ungrateful behavior people displayed after receiving a gift horse was so common that this proverb developed from it.
