Forms

praefātiō f (genitive praefātiōnis); third declension[1]

Etymology

It is from Latin praefor (“to say beforehand”) + -tiō,[2][1][3] and that verb is a compound of prae- (“before”) and for (“to speak”).[1][4] De Vaan traces for to Proto-Italic *fā- (“to speak”) and Proto-Indo-European *bheh2- (“to speak”).[5]

Earliest recorded meaning

Köbler's earliest source is Cicero,[6] who in the Verrines asks what formula went with a gift: quae porro praefātiō tuae dōnātiōnis fuit?[2][7] The sense is a set form of words said beforehand.[8][9]

Semantic evolution

In religious and public language it was the formula spoken before a rite or act: Livy has the praefātiō sacrōrum, Pliny the Elder that of a triumph, and Suetonius the old formula of the fetial priests.[8][9][7] Pliny also uses it of a phrase such as “by your leave” put before a rustic or foreign word, and Suetonius of words of clemency put before a harsh sentence.[8][7] In law it was a preliminary negotiation before a contract.[9][2]

The sense of a preface to a speech or book appears in Pliny the Elder and later.[2][8] In the Church it named the preface of the Mass,[10][4] and in Britain Theodore and Bede use it of the preface of a book.[11] English preface, first “an introduction to the canon of the Mass”, came from medieval Latin prefatia, partly through Old French.[4]
