So apparently there are two types of Vth for a MOSFET

How can I tell the saturation apart from linear?
Right now I am simulating a voltage sweep (on the Gate) of a transistor and the sim results give a saturation and a linear Vth. Now from what I understand saturation depends on whether the drain is higher than the gate by the threshold voltage. So how am I suppose to know if my drain voltage of -0.1V is higher than the Gate voltage by the threshold if my gate voltage is changing?
And my most general question...does Vth change with Gate voltage?
edit: Source is at 0V, and this is a pchannel mosfet
