To reconstruct something means to build or create it again after it has been damaged, destroyed, or lost. When archaeologists find ancient pottery shards scattered across a dig site, they carefully reconstruct the original vessel by figuring out how the pieces fit together. After a tornado damages a town, builders reconstruct homes and schools to restore the community.

Reconstructing often requires investigation and interpretation, not simply copying what existed before. When scientists reconstruct what a dinosaur looked like, they study fossilized bones and make educated guesses about skin, muscles, and behavior. When historians reconstruct events from the past, they piece together evidence from letters, artifacts, and records to understand what happened.

You might reconstruct your memory of a field trip by thinking through the day's events in order, or reconstruct a story by remembering key details. In American history, Reconstruction (with a capital R) refers specifically to the period after the Civil War when the nation worked to rebuild and reunify. The process of reconstructing always involves careful thought about how to put pieces back together in a way that makes sense.
