IPA: /ˈprɛfəsər/
KK: /ˈprɛfəsər/
A person who writes a preface, which is an introduction to a book or other written work.
The prefacer provided important context for the readers before they started the book.
Prefacer → It is formed from "pre-" (meaning before) and "facere" (meaning to do or make). A prefacer is someone who makes or does something before the main content, typically introducing it.
Think of someone who 'does' ('facere') something 'before' ('pre-') the main event — that's why a prefacer introduces what comes next.
