A liquid is a form of matter that has an almost-fixed volume but no set shape. It is wet, and it takes the shape of the container. It is very difficult to compress a liquid.

A liquid is one of the three states of matter. Examples of liquid are water or oils. Your blood is a liquid too.

If a liquid is at rest in a uniform gravitational field, the pressure p at any point is given by

p = ρgz

where ρ is the density of the liquid (assumed constant) and z is the depth of the point below the surface. Note that this formula assumes that the pressure at the free surface is zero.
