In answer to your question - Aircraft manufacturers use V-speeds to describe standard speeds for aircraft performance.
V - mean Velocity
M - means Minimum
C - means Control or Controllable
A - A was tacked on and that means clean or dirty (as in gear and flaps down or up), because this particular aircraft has the same speed posted for Flaps up or Down, in some aircraft these speeds would be different.
