The expression ‘beside oneself’ is believed by some to have originated in the late seventeenth century. It is thought to derive from the Greek word, ‘ekstasis’, which means to stand outside of oneself. This suggests the idea of being so overwhelmed by an emotion that one cannot think clearly. The adverb ‘beside’ was then added to this to create the phrase ‘beside oneself’, to indicate the sense of being outside oneself.
