The word "吕氏春秋" is formed from three components: "吕" is the surname Lü, "氏" functions as a possessive marker indicating 'of the clan', and "春秋" means 'spring and autumn' but here specifically denotes historical annals. Together, they create a title meaning "The Spring and Autumn Annals of the Lü Clan", directly referring to the text associated with Lü Buwei.
