means The process of rebuilding something that's been broken or torn down — or, in American history, the fraught post-Civil War effort to rebuild the South and establish rights for freed Black Americans.

from Built from Latin re- ('again') plus constructio ('a piling up, building'), itself from struere ('to build, heap up') — the same root behind 'structure' and 'construct.' As a general word for rebuilding, it's a straightforward Latin compound; its weighty capital-R meaning in U.S. history comes later, when the word was pressed into service for a specific, painful decade of trying — and largely failing — to build something just out of the ruins of slavery.
