Nissan Tsuru etymology: What does its name mean?

For many years the Nissan Tsuru, basically a B13 Sentra, was the best selling car in Mexico, but what does its name mean, if anything?

The Nissan Tsuru is named after the Japanese word for crane: ヅル or dzuru. That’s crane the bird, not crane the piece of mechanical equipment.

With tightening safety regulations, the Tsuru may soon go out of production in Mexico.
