Question
"Las Comprendidas"
In my understanding, Comprendida comes from "comprender" (understand). However, not sure how to understand it in the example below. Does it have a specific meaning which is not exactly related with "understanding"?"y se llaman líneas divisorias"
Does this sentence refer to the "dos líneas verticales"? It looks the subject has been "las figuras y silencios" and it seems odd that the subject has been changed to "lineas verticales". Is this normal in Spanish?
