IPA: /əˈkreɪziə/
KK: /əˈkreɪziə/
A lack of self-control or the inability to act according to one's better judgment.
His acrasia led him to indulge in unhealthy habits despite knowing the consequences.
Acrasia is derived from the Greek "akrasia" (ἀκρασία), which is formed from "a-" (meaning without) and "kratos" (meaning power or strength). The term originally referred to a lack of self-control or weakness of will, indicating a state of being without power over one's actions.
Think of 'without power' ('a-' means without and 'kratos' means power) to remember that acrasia refers to a lack of self-control.
