There are two kinds of space, conceptually speaking. One is more properly termed "volume", and we all have an intuitive notion of what this means. A volume the simultaneously considered set of points existing on the interior of a static, finite, simultaneous enclosing boundary.
More generally, space may be considered to be a measure of how much freedom of motion is available. Space is literally the space between things; the further apart things are, the more space there is between them. Separation is actually measured with time: distance means time. So space is that which separates things. Direction of separation is also important, when you are considering more than one thing angles arise. So we have amount and direction of separation -- that is what space is. Amount of separation is measured by time of transit, and direction of separation is a matter of angular trajectory.
So ultimately we can say that space is the "passage" of time in all directions. More specifically, space is the memory of time's passage in at least four directions (this is enough to define all other directions).
Volumes are regions where the passages are regenerative in time, so appear static.
