  3. \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.
