Lorem Ipsum is placeholder text used in design, publishing, and web development to show how a layout looks before real content is ready. It comes from a scrambled passage of Cicero's De Finibus Bonorum et Malorum written in 45 BC, making it over 2,000 years old.

It's derived from Latin but heavily modified. The original passage from Cicero has been scrambled and nonsense syllables inserted, so it reads as Latin-like but has no meaning. Native Latin speakers won't understand it as coherent text.

Using real text in mockups can distract reviewers who start reading the content instead of evaluating the design. Lorem Ipsum keeps attention on layout, typography, and spacing. It also closely mimics the character distribution and rhythm of natural English text.

Only as a temporary placeholder during development. Lorem Ipsum should always be replaced with real content before launch. Leaving placeholder text on a live site harms SEO, looks unprofessional, and confuses users.

The full original passage from Cicero translates roughly to: 'There is no one who loves pain itself, who seeks after it and wants to have it, simply because it is pain...' The Lorem Ipsum version is a scrambled excerpt and has no literal meaning in its modified form.
