Ish. Yes, the basic shapes come from what was possible back then, but some varieties ended up being more popular because they do work better. Sadly I lack the English vocabulary to describe the difference between penne liscie and penne rigate...

Looks like the difference is one has longitudinal ridges, and the other is smooth.

This is what ChatGPT has to say about the difference. Does it capture your view of the matter?

Penne liscie and penne rigate are both types of penne pasta, but they differ in their surface texture:

1. *Penne Liscie*: This type of penne has a smooth surface. The word "liscie" in Italian means "smooth." Due to its smooth texture, it generally holds lighter sauces better, as the surface doesn't trap as much sauce.

2. *Penne Rigate*: In contrast, penne rigate has a ridged surface. "Rigate" means "ridged" or "grooved" in Italian. These ridges or grooves are excellent for holding onto thicker, heartier sauces, as they provide more surface area for the sauce to adhere to.

The choice between the two usually depends on the type of sauce being used and personal preference. Penne rigate's ability to hold more sauce makes it a popular choice for many robust and creamy sauces.
