Note
The sense of growth by stages, where developed answers rudimentary. John Lubbock's The Origin of Civilisation traces ideas from "a rudimentary religion" up "into a more developed condition," and that ladder still shapes how the word is used of theories, characters and arguments.
- 4Of land or an area: built on, or provided with roads and services such as water and power.
Most of the floodplain is now developed, leaving little open ground.
A developed lot with water, sewer and power already in place costs far more than raw land at the edge of town.
Note
Land-use vocabulary: a plot, district or floodplain can count as developed when buildings, roads, drainage or utilities have been added to it, and the label matters in zoning and real estate. Its opposite is undeveloped or raw land. The stress falls on what has been built: homes and shops, but also the roads and services that make a place work.
Less common meaning
- 5Processed and fixed so that a visible image appears on the film: a negative, or a positive for slide film.

Similarprocessed
Oppositeundeveloped, unprocessed
Note
A darkroom term with two steps folded into it. Development makes the latent image appear, and fixing makes it permanent; only then is film developed in this sense. What appears depends on the stock: a negative on ordinary film, or a positive on reversal (slide) film. The adjective comes straight from the verb's photographic use, to bring out images latent in film.
