Etymology

The word "directional" combines "direction," derived from Latin directio (from dirigere, meaning "to guide or align"), with the suffix "-al," which forms adjectives meaning "pertaining to." The root "direct" implies linear or purposeful movement, while "-al" generalizes this into a descriptive quality. Over time, "directional" evolved to describe anything oriented or responsive to a specific path or focus, reflecting its Latin roots in guidance and alignment.

  3. The satellite uses a directional antenna to transmit data efficiently.
