Undirected graphs are often used to model social networks where friendships are mutual.

To analyze reachability in the network, we searched for an undirected path that connects the two vertices despite the mixed orientations of edges.

During the experiment, the particles moved undirectedly, making it difficult to predict their paths.

The script's chaotic structure made it undirectable, frustrating every director who tried to bring it to life.

The cunning spy tried to undirect the investigators by planting false evidence.

Her undirect answer made me wonder if she was hiding something.

Despite the muddy weather, he managed to keep the porch undirty all week.

She tried to undirty the antique vase without damaging the glaze.

In the draft diagram the arrows were labeled undirectionally, so the editor corrected the term.

In algorithms class, we modeled the social network as an undirected graph to simplify analysis of mutual friendships.
