Immense means extremely large, beyond easy measure. An immense building, immense pressure, immensely grateful.
It works for physical size and for abstract quantity alike — immense wealth, immense relief, immense damage — and it is stronger than huge in tone if not in dimension. Immensely is used as a plain intensifier meaning very. Note that the word literally means unmeasured, from in- plus mensus, so an immense thing is one that cannot be taken in; and immensity, which is the noun.

Latin immensus is in-, not, plus mensus, measured. Measure, dimension and immensity come from the same measuring, so immense means beyond measuring.
