Versus


Definition:

  • (prep.) Against; as, John Doe versus Richard Roe; -- chiefly used in legal language, and abbreviated to v. or vs.

Example Sentences:

  • (1) It was found that linear extrapolations of log k' versus ET(30) plots to the polarity of unmodified aqueous mobile phase gave a more reliable value of log k'w than linear regressions of log k' versus volume percent.
