IPA: /ˈɛpɪˌdʒiːn/
KK: /ˈɛpɪˌdʒin/
Relating to something that is formed or occurs on or just beneath the surface of the earth.
The geologist studied the epigene features of the landscape.
Epigene is derived from "epi-" (meaning upon or over) and "genes" (from Greek "genes", meaning born of or produced by). The term refers to something that is produced or formed upon a surface, particularly in geological contexts.
Think of 'epi-' meaning 'upon' and 'genes' meaning 'produced by' — this helps you remember that epigene refers to something formed upon a surface.
