azimuthal positive

Morphology

azimuthal = azimuth (semi-transparent) = azimuth + al

The adjective is formed regularly from the noun 'azimuth' with '-al', and its meaning is directly 'relating to azimuth'.

Etymology

Azimuthal comes from azimuth, which in turn came from the Arabic word samt meaning 'direction'. So azimuthal is used for measurements of 'direction' — the angle or bearing around a point, which is why astronomers and mapmakers use it to point telescopes or show compass directions.
