imprimatur

The word 'imprimatur' is a direct borrowing from Latin, where it is the 3rd person singular present subjunctive passive of the verb 'imprimere', meaning 'let it be printed'. This verb itself is composed of 'in-' (into, on) and 'premere' (to press). Historically, the term entered English in the 17th century from the phrase "imprimatur" found on early printed books, signifying official license to publish granted by the Catholic Church. The literal sense, 'let it be pressed (onto the page)', evolved into the abstract meaning of formal sanction or approval, particularly for the publication of religious or doctrinal works, and later generalized to any authoritative endorsement.
