IPA: /ˈpɜːrviəs/
KK: /ˈpɜrvɪəs/
Able to allow things to pass through, such as water or air; not blocked or closed off.
The soil in this area is pervious, allowing rainwater to seep into the ground easily.
Pervious → It is formed from "per-" (meaning through) and "via" (meaning way or road). The word "pervious" means allowing passage through, as in a way that is open or accessible.
Think of something that allows things to pass 'through' ('per-') a 'way' ('via') — that's why pervious means open to passage.
