 This example demonstrates how to perform hierarchical merging on region
 boundary Region Adjacency Graphs (RAGs). Region boundary RAGs can be
-contructed with the :py:func:`skimage.future.graph.rag_boundary` function.
+constructed with the :py:func:`skimage.future.graph.rag_boundary` function.
 The regions with the lowest edge weights are successively merged until there
 is no edge with weight less than ``thresh``. The hierarchical merging is done
 through the :py:func:`skimage.future.graph.merge_hierarchical` function.
