From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Tide \Tide\, n. [AS. t[c6]d time; akin to OS. & OFries. t[c6]d,
      D. tijd, G. zeit, OHG. z[c6]t, Icel. t[c6][?], Sw. & Dan.
      tid, and probably to Skr. aditi unlimited, endless, where a-
      is a negative prefix. [fb]58. Cf. {Tidings}, {Tidy}, {Till},
      prep., {Time}.]
      1. Time; period; season. [Obsoles.] [bd]This lusty summer's
            tide.[b8] --Chaucer.
                     And rest their weary limbs a tide.      --Spenser.
                     Which, at the appointed tide, Each one did make his
                     bride.                                                --Spenser.
                     At the tide of Christ his birth.         --Fuller.
      2. The alternate rising and falling of the waters of the
            ocean, and of bays, rivers, etc., connected therewith. The
            tide ebbs and flows twice in each lunar day, or the space
            of a little more than twenty-four hours. It is occasioned
            by the attraction of the sun and moon (the influence of
            the latter being three times that of the former), acting
            unequally on the waters in different parts of the earth,
            thus disturbing their equilibrium. A high tide upon one
            side of the earth is accompanied by a high tide upon the
            opposite side. Hence, when the sun and moon are in
            conjunction or opposition, as at new moon and full moon,
            their action is such as to produce a greater than the
            usual tide, called the {spring tide}, as represented in
            the cut. When the moon is in the first or third quarter,
            the sun's attraction in part counteracts the effect of the
            moon's attraction, thus producing under the moon a smaller
            tide than usual, called the {neap tide}.
      Note: The flow or rising of the water is called flood tide,
               and the reflux, ebb tide.
      3. A stream; current; flood; as, a tide of blood. [bd]Let in
            the tide of knaves once more; my cook and I'll
            provide.[b8] --Shak.
      4. Tendency or direction of causes, influences, or events;
            course; current.
                     There is a tide in the affairs of men, Which, taken
                     at the flood, leads on to fortune.      --Shak.
      5. Violent confluence. [Obs.] --Bacon.
      6. (Mining) The period of twelve hours.
      {Atmospheric tides}, tidal movements of the atmosphere
            similar to those of the ocean, and produced in the same
            manner by the attractive forces of the sun and moon.
      {Inferior tide}. See under {Inferior}, a.
      {To work double tides}. See under {Work}, v. t.
      {Tide day}, the interval between the occurrences of two
            consecutive maxima of the resultant wave at the same
            place. Its length varies as the components of sun and moon
            waves approach to, or recede from, one another. A
            retardation from this cause is called the lagging of the
            tide, while the acceleration of the recurrence of high
            water is termed the priming of the tide. See {Lag of the
            tide}, under 2d {Lag}.
      {Tide dial}, a dial to exhibit the state of the tides at any
      {Tide gate}.
            (a) An opening through which water may flow freely when
                  the tide sets in one direction, but which closes
                  automatically and prevents the water from flowing in
                  the other direction.
            (b) (Naut.) A place where the tide runs with great
                  velocity, as through a gate.
      {Tide gauge}, a gauge for showing the height of the tide;
            especially, a contrivance for registering the state of the
            tide continuously at every instant of time. --Brande & C.
      {Tide lock}, a lock situated between an inclosed basin, or a
            canal, and the tide water of a harbor or river, when they
            are on different levels, so that craft can pass either way
            at all times of the tide; -- called also {guard lock}.
      {Tide mill}. (a) A mill operated by the tidal currents.
            (b) A mill for clearing lands from tide water.
      {Tide rip}, a body of water made rough by the conflict of
            opposing tides or currents.
      {Tide table}, a table giving the time of the rise and fall of
            the tide at any place.
      {Tide water}, water affected by the flow of the tide; hence,
            broadly, the seaboard.
      {Tide wave}, [or] {Tidal wave}, the swell of water as the
            tide moves. That of the ocean is called primitive; that of
            bays or channels derivative. --Whewell.
      {Tide wheel}, a water wheel so constructed as to be moved by
            the ebb or flow of the tide.
