A preannouncement is a presequence for an announcement of news.
It consists of a turn in which the announcing participant checks on the newsworthiness of the item, and may also consist of a turn in which the recipient allows or disallows the newsworthiness of the item before beginning a request-acceptance or question-answer sequence to elicit the announcement.
The first turn in the following exchange is a preannouncement:
- A: Oh, guess what.
- B: What?
- A: Professor Deelies put another book on his order.
