Retard

Re*tard"\, n. Retardation; delay.

Retard, or Age, of the tide, the interval between the transit of the moon at which a tide originates and the appearance of the tide itself. It is found, in general, that any particular tide is not principally due to the moon's transit immediately proceeding, but to a transit which has occured some time before, and which is said to correspond to it. The retard of the tide is thus distinguished from the lunitidal interval. See under Retardation. --Ham. Nav. Encyc.
