IPA: /haɪˈpoʊdʒiən/
KK: /haɪˈpoʊdʒiən/
Relating to something that is located or occurs underground.
The hypogean environment is home to many unique species that have adapted to life without sunlight.
Hypogean is formed from "hypo-" (meaning under) and "ge" (from Greek "gē", meaning earth). The word describes something that is situated or occurring beneath the earth's surface.
Think of 'under' ('hypo-') and 'earth' ('ge') to remember that hypogean refers to something that is below the earth.
