account: [14] Account is of Old French origin. It was formed from compter, conter ‘count’ (which derived from Latin computāre) and the prefix a-. Its original meaning in English, too, was ‘count’ or ‘count up’; this had disappeared by the end of the 18th century, but its specialized reference to the keeping of financial records is of equal antiquity. Account for, meaning ‘explain’, arose in the mid 18th century. => count
