Century Dictionary and Cyclopedia

1. n. A statement or series of statements introducing a discourse, book, or other composition; a series of preliminary remarks, either written or spoken; a prelude. A preface is generally shorter than an introduction, which contains matter kindred in subject, and additional or leading up to what follows; while a preface is usually confined to particulars relating to the origin, history, scope, or aim of the work to which it is prefixed.
2. n. [cap, or lowercase] In liturgics, the introductory section of the anaphora; the solemn eucharistic thanksgiving and ascription of glory introducing the canon. The Preface is found of the same type in all liturgies. It begins with the Sursum Corda, generally preceded in early and Oriental forms by the apostolic (2 Cor. xiii. 14) or a similar benediction. After an exhortation to give thanks (Response: “It is meet and right …”), the Preface in the narrower sense begins with the affirmation (contestation) “It is very [truly] meet, etc., to give thanks …” The reason for thankfulness is given in the central division of the form. This in early and Oriental liturgies is invariable, and still retains much of its original character of an extended ascription of glory to God and rehearsal of his dealings with man from the Creation and Fall onward. In Western liturgies a number of proper Prefaces is provided, varying according to the day or season. Probably these were originally sections of the primitive Preface or of the earlier part of the Canon, selected as appropriate to the season or modeled on such sections. The Preface terminates with the Sanctus. Also, in Gallican uses, contestation, illation, immolation.
3. n. A title; an introductory or explanatory epithet.
4. To give a preface to; introduce by preliminary written or spoken remarks, or by an action significant of what is to follow.
5. To say as a preface; write or utter in view or explanation of what is to follow.
6. To front; face; cover.
7. To give a preface; speak, write, or do something preliminary to later action.
