what does straight from the horses mouth mean

Sometimes we hear phrases said and wonder what the person who’s using them actually means. For instance, someone may tell you that something came “straight from the horse’s mouth” leaving you to imagine a talking horse but that probably isn’t what they mean.

When someone tells you that it came “straight from the horse’s mouth” what they’re really telling you is that they got the information that they’re sharing with you directly from a person who has personal knowledge of the matter.

Origin of the Phrase

The phrase “straight from the horse’s mouth” comes from horse racing. It alludes to what a perfect racehorse’s bite would be like – something that was also used to tell just how old the horse really was. The idea that lies behind this phrase is that someone has come directly from examining the horse’s mouth to give you some information about the horse’s age and condition – two important pieces of information that would then help a person determine the horse’s value.

This practice only has to do with buying a horse, not racing them since when it comes to horse racing the punter is already familiar with the horse’s age. Even if the punter was suspicious of the horse’s age it’d still be somewhat difficult to imagine them going to the stable to examine the horse’s teeth in order to ascertain their age.

The earliest written instance of this phrase was found in Bell’s Life in London and Sporting Chronicle on Sunday, September 22, 1861. While the phrase probably didn’t disappear afterward, we don’t see it in the written form again until Friday, July 20, 1900, where it was used in the column This Busy World which was found in The Manchester Weekly Times. The phrase really started to rise up in popularity around the 1920s though.

Over the years the practice of using a horse’s teeth to determine its age has given rise to other phrases that predate “straight from a horse’s mouth.” Another popular one is “long in tooth” which has to do with the fact that as a horse gets older their teeth will grow longer. This phrase is oftentimes used to describe someone who’s older. There’s also the phrase “don’t look a gift horse in the mouth” which means that you shouldn’t be critical about a gift you’ve received.

Once again we see this idiom in printed form in May 1913. Here the Syracuse Herald newspaper printed, “I got a tip yesterday, and if it wasn’t straight from the horse’s mouth it was jolly well the next thing to it.” While this still references the horse racing world people in this century believed it did so in a different way. Here people say that it was related to the bets that were placed on the likely winner. Such bets would be circulated among people who were well trusted. These were usually people who were close to the horse and knew him or his trainers and stable workers well.

Another source suggests that this phrase was derived from the fact that many trainers were known to lie about how old their horses were. This is why they’d check the horse’s mouth in order to be able to get a reliable indication of how old the horse was.

There really is no difference in what this saying means though. It’s still thought to mean that the advice you’ve received is so solid that it’s like hearing the information from the horse itself.

Meaning of the Phrase

Now that we know that “straight from the horse’s mouth” is an idiom that comes from the horse racing world we may wonder what an idiom is and what this one in specific means. To begin with, you should know that an idiom is a word or a group of words that has a figurative meaning attached to it. Therefore what the word(s) mean isn’t easily deduced from the literal meaning of the words themselves. This is why you have to look more at the phrase itself instead of the words in specific.

This saying was coined somewhere around the turn of the twentieth century within horse racing circles. With this in mind, we can think of the information as having come from the racehorse himself. Some people believe that the saying was first used in reference to checking a horse’s teeth to see what their physical shape was like so you’d know if he could win a race. While this saying may have originated here, today it’s used in a lot of different situations when someone is trying to say that they’ve received the information from an impeccable source – that they’ve confirmed the information from the best source possible.
