1. (of a crystal or mineral) lacking well-defined crystal faces or geometric form
Usage: mineralogy; geology
2. (of an aircraft wing) angled downward from the fuselage; having a negative dihedral angle
Usage: aeronautics

Examples

• The anhedral feldspar crystals in the granite showed no distinct geometric boundaries.
• Geologists identified the mineral as anhedral because it lacked the sharp faces typical of well-formed crystals.
• The aircraft's anhedral wing design helped improve stability during flight.
• Unlike euhedral quartz, the anhedral variety formed in the spaces between other minerals.
• The fighter jet featured anhedral wings to reduce its aerodynamic profile.
