What does decreased in MAGNITUDE mean?

I think magnitude means how much of something or how long the sides are or the angle.
smaller, size of scalar or magnitude of vector
if a vector is defined by
V = x + i y
then its magnitude |V| is sqrt(x^2 + y^2)
if you are going 5 mph east
and 5 mph north
then the magnitude of your velocity is the speed = sqrt(5^2+5^2) = 5 sqrt 2
