- the state or quality of being ample, especially as to breadth or width; largeness; greatness of extent.
- large or full measure; abundance; copiousness.
- mental range, scope, or capacity.
- the absolute value of the maximum displacement from a zero value during one period of an oscillation.
- the maximum deviation of an alternating current from its average value.
- the arc of the horizon measured from the east or west point to the point where a vertical circle through a heavenly body would intersect the horizon.
- argument (def. 8b).
- greatness of extent; magnitude
- abundance or copiousness
- breadth or scope, as of the mind
- the angular distance along the horizon measured from true east or west to the point of intersection of the vertical circle passing through a celestial body
- (of a complex number) the angle that the vector representing the complex number makes with the positive real axis. If the point (x, y) has polar coordinates (r, θ), the amplitude of x + i y is θ, that is, arctan y/x
- the maximum variation from the zero or mean value of a periodically varying quantity
