Webster's 1913 Dictionary
  1. \Fluc"tu*ate\, v. i. [imp. & p. p. {Fluctuated}; p.
    pr. & vb. n. {Fluctuating}.] [L. fluctuatus, p. p. of
    fluctuare, to wave, fr. fluctus wave, fr. fluere, fluctum, to
    flow. See {Fluent}, and cf. {Flotilla}.]
    1. To move as a wave; to roll hither and thither; to wave; to
       float backward and forward, as on waves; as, a fluctuating
       field of air. --Blackmore.
    2. To move now in one direction and now in another; to be
       wavering or unsteady; to be irresolute or undetermined; to
    Syn: To waver; vacillate; hesitate; scruple.
    Usage: To {Fluctuate}, {Vacillate}, {Waver}. -- Fluctuate is
           applied both to things and persons and denotes that
           they move as they are acted upon. The stocks
           fluctuate; a man fluctuates between conflicting
           influences. Vacillate and waver are applied to persons
           to represent them as acting themselves. A man
           vacillates when he goes backward and forward in his
           opinions and purposes, without any fixity of mind or
           principles. A man wavers when he shrinks back or
           hesitates at the approach of difficulty or danger. One
           who is fluctuating in his feelings is usually
           vacillating in resolve, and wavering in execution.
  2. \Fluc"tu*ate\, v. t.
    To cause to move as a wave; to put in motion. [R.]
          And fluctuate all the still perfume.     --Tennyson.
