   • The conical or curved nose of a projectile: In ballistics and aeronautics, an ogive is the tapered, curved front section of a missile, rocket, or bullet, designed to reduce aerodynamic drag.

Examples of Usage

• Noun (Architecture):

  • The cathedral's ceiling was supported by elegant stone ogives.
  • Gothic architecture is famous for its use of the ogive in vaulting.

• Noun (Ballistics/Aeronautics):

  • The missile's ogive is designed to minimize air resistance during flight.
  • Engineers optimized the rocket's ogive for better supersonic performance.

Advanced Usage

• "Ogive curve": In statistics, an ogive is a graph that represents the cumulative frequency distribution of data, often shown as a curve.
  • The ogive curve showed the cumulative percentage of test scores.

Variants and Related Words

• Ogive arch (n): Another term for a pointed arch in architecture.
• Secant ogive (n): A specific ballistic shape where the curve is a segment of a circle that intersects the projectile's body line.
• Tangent ogive (n): A common ballistic shape where the curve is tangent to the projectile's cylindrical body.

Synonyms

• Pointed arch (for architectural meaning).
• Nose cone (for ballistic/aeronautical meaning, though "nose cone" is more general).

Related Phrases
