Origin of azimuthMiddle English and Old French azimut from Arabic as-sum?t from as from al, the + sum?t, plural of samt, way, path
- The horizontal angular distance from a reference direction, usually the northern point of the horizon, to the point where a vertical circle through a celestial body intersects the horizon, usually measured clockwise. Sometimes the southern point is used as the reference direction, and the measurement is made clockwise through 360°.
- The horizontal angle of an observer's bearing, measured clockwise from a reference direction such as true north.
- The horizontal angle of a projectile's motion, measured relative to a reference direction such as true north.
Origin of azimuthMiddle English azimut from Old French from Arabic as-sumūt pl. of as-samt the way, compass bearing al- the samt way ( from Latin sēmita path ; see mei-1 in Indo-European roots.)

The trajectory of an angle measured in degrees going clockwise from a base point. A disk azimuth alignment test checks for the correct positioning of the read/write head to the track.
