If two things are like "two peas in a pod," then they’re very similar to one another (if not all but identical). | Culture Club/GettyImagesWell, like a lot of standard English similes, the origins of "two peas in a pod" lie a little further back in time than you might think. As a result, we’ve had two peas in a pod (rather than a pair of peases) ever since. | Heritage Art/Heritage Images/Getty ImagesNo matter whether or not Lyly made this phrase up himself, why singled out peas as an example of similarity here? And although in an era of supermarkets and freezer shopping we’re perhaps less used to growing and podding peas today, the phrase nonetheless still works and holds true nearly 500 years later.
