IPA: /ˌɛndəˈdʒɛnəsli/
KK: /ɛnˈdɔdʒənəsli/
In a way that originates from within an organism or system, rather than from external factors.
The hormones were produced endogenously, affecting the body's metabolism.
Endogenously → It is formed from "endo-" (from Greek "endon", meaning within) and "genous" (from Greek "genes", meaning born of or produced by). The word "endogenously" refers to something that originates from within an organism or system.
Think of something that is 'born from within' — 'endo-' means within, and 'genous' means produced. This helps you remember that endogenously refers to processes that originate internally.
