Either the battery has gone dead and does not have enough power to engage the starter and crank the engine or the starter has gone bad and is due for a rebuild or replacement. Have the battery checked for voltage, should be a little more than 12 volts, and have a load test done to the battery. If the battery checks out ok then you should have the starter checked. Quick checks you can make are, check the battery terminals for extreme corrosion and check that they are tight.
