What is standard deviation conceptually?

Definition: Standard deviation is the measure of dispersion of a set of data from its mean. It measures the absolute variability of a distribution; the higher the dispersion or variability, the greater is the standard deviation and greater will be the magnitude of the deviation of the value from their mean.

What does the mean deviation tell you?

What if standard deviation is greater than mean?
