psyche: [17] Like Latin animus (source of English animal), Greek psūkhé started out meaning ‘breath’ and developed semantically to ‘soul, spirit’. English adopted it via Latin psychē in the mid-17th century, but it did not really begin to come into its own until the middle of the 19th century, when the development of the sciences of the mind saw it pressed into service in such compound forms as psychology (first recorded in 1693, but not widely used until the 1830s) and psychiatry (first recorded in 1846), which etymologically means ‘healing of the mind’. => psychiatry, psychology[psyche etymology, psyche origin, 英语词源]
