IPA: /ˈkrɪb.rəs/
KK: /ˈkrɪbrəs/
Having holes or openings, similar to a sieve.
The cribrous material allowed water to pass through while filtering out larger particles.
Cribrous is derived from the Latin word "cribrosus" (meaning full of holes or perforated), which comes from "cribrum" (meaning sieve or strainer). The suffix "-ous" indicates possessing or full of. Thus, cribrous refers to something that is full of holes or perforations, resembling a sieve.
Think of a sieve or strainer ('cribrum') that is 'full of holes' ('cribrosus') — that's why cribrous describes something that has many holes.
