IPA: /ˈɪmpətəns/
KK: /ˈɪmpətəns/
The condition of being unable to achieve or maintain an erection, often referred to as erectile dysfunction.
Many men experience impotence at some point in their lives, which can be a source of stress and anxiety.
Impotence is formed from "in-" (meaning not) and "potentia" (from Latin, meaning power or ability). The word describes a state of lacking power or ability, particularly in a physical or functional sense.
Think of 'not' ('in-') having 'power' ('potentia') — that's why impotence means lacking power or ability.
