  Submarine \Sub`ma*rine"\, n.
     1. A submarine boat; a ship that can travel under the surface
        of the water. Most such ships are ships of war, as part of
        a navy, but submarines are also used for oceanic research.
        Also called {sub} and (from the German U-Boot) {U-boat}.
        esp., Nav., a submarine torpedo boat; -- called specif.


        {submergible submarine} when capable of operating at
        various depths and of traveling considerable distances
        under water, and {submersible submarine} when capable of
        being only partly submerged, i.e., so that the conning
        tower, etc., is still above water. The latter type and
        most of the former type are submerged as desired by
        regulating the amount of water admitted to the ballast
        tanks and sink on an even keel; some of the former type
        effect submersion while under way by means of horizontal
        rudders, in some cases also with admission of water to the
        ballast tanks.

From The Collaborative International Dictionary of English v.0.48 [gcide]:

  Sub- \Sub-\ [L. sub under, below; akin to Gr. ?, Skr. upa to,
     on, under, over. Cf. {Hypo-}, {Super-}.]
     1. A prefix signifying under, below, beneath, and hence
        often, in an inferior position or degree, in an imperfect
        or partial state, as in subscribe, substruct, subserve,
        subject, subordinate, subacid, subastringent, subgranular,
        suborn. Sub- in Latin compounds often becomes sum- before
        m, sur before r, and regularly becomes suc-, suf-, sug-,
        and sup- before c, f, g, and p respectively. Before c, p,
        and t it sometimes takes form sus- (by the dropping of b
        from a collateral form, subs-).
        [1913 Webster]
  
     2. (Chem.) A prefix denoting that the ingredient (of a
        compound) signified by the term to which it is prefixed,is
        present in only a small proportion, or less than the
        normal amount; as, subsulphide, suboxide, etc. Prefixed to
        the name of a salt it is equivalent to basic; as,
        subacetate or basic acetate. [Obsoles.]
        [1913 Webster]
