A sketch is usually a quick, rough way to express an idea, most often as a drawing but also in writing or performance.

What “sketch” means

  • A quick, rough drawing that shows the main features of an object or scene, without full detail or polish.
  • A tentative draft or outline of something, like an early version of a story, plan, or design.
  • A short description of a person, event, or idea (for example, a “character sketch” in literature).
  • A short, usually light or comic performance piece, like a comedy sketch on a TV show.
  • In music, a brief and simple composition or idea, often on piano.

In modern design and tech, Sketch (capital S) can also mean a specific design software used for UI/UX, mockups, and prototypes on Mac.

Mini examples

  • Art: An artist makes a pencil sketch of a city skyline before painting the full canvas.

Quick storytelling-style view

Imagine you have an idea for a new café: first you grab a notebook and sketch the floor plan with rough tables and a counter. Then you write a short character sketch of your ideal customer to understand who you’re serving. Later, a comedy group could write a funny sketch about awkward first dates in that café, turning your simple drawing into a stage scene. And if you take it digital, you might open Sketch on your Mac to design the café’s app for online orders.

TL;DR: A sketch is any quick, not‑yet‑finished way to capture an idea — as a drawing, outline, short description, or short performance — and “Sketch” can also be a popular digital design tool.
