The process of making something thicker or denser.
The inspissation of the sauce made it perfect for the pasta.
Inspissation → It is formed from "in-" (meaning into) and "spissare" (meaning to thicken). The word refers to the process of making a liquid thicker or more concentrated by removing some of its water content.
Think of 'thickening' something by adding more substance ('spissare') into it ('in-'). This helps you remember that inspissation means the act of thickening.
