Imagine a city park where they begin to build a temporary stage for a big festival. The residents are outraged: the noise, the fences, the trucks everywhere. But while the construction is going on, some people quietly put up with the inconvenience. Meanwhile, the workers put up a huge stage, scaffolding, banners, and lighting — they are literally erecting everything on site to make the festival happen. Here, “put up” means to erect, build, or attach something physically.
Examples:
The city always puts up [pʊt ʌp] a large Christmas tree in the main square.
We need to put up a fence around the garden to keep the dogs out.
