Preso
What does Preso mean?
Preso is informal English workplace shorthand for a presentation. Depending on the conversation, it can mean the talk itself or the slides prepared for it.
The term appears in casual messages such as requests to review a presentation before a meeting. It does not identify a particular file format, audience, or length. When a colleague asks for a preso, clarify whether they want the slide file, a rehearsal, or the finished presentation delivered to an audience.
Illustrative workplace example
A manager writes, “Can you send the client preso before lunch?” The team replies with the slide deck and asks whether speaker notes should be included. In a formal project plan, they call the output a client presentation.
How it differs from related ideas
A slide deck is the collection of slides. A presentation is the broader act or material used to communicate an idea and may include a demonstration or discussion. Preso is a casual abbreviation, so spelling out presentation is clearer for unfamiliar audiences.
Say it in plain English
Please send me the presentation.
