What is the difference between partial pressure of a liquid and vapur pressure of the liquid?
Is the anything called partial vapur pressure? If so difference between all the 3 is ?

It should be "partial pressure of vapour of a liquid". Vapour pressure of a liquid the the pressure of the vapour present over the surface of a liquid. Partial pressure comes into play when there is more than one component in the gaseous mixture i.e. for a solution with volatile liquid components, there will be more than one kind of vapour present over the surface. Partial Vapour Pressure and Partial Pressure are same.
