"Sinistral" means relating to or located on the left side. âŦ ī¸ It's the opposite of "dextral," which refers to the right. In biology, it often describes shells that coil counterclockwise. It can also refer to left-handedness. Historically, "sinistral" had negative connotations, associating the left with awkwardness or evil. Nowadays, it's simply a descriptive term without those implications.
