Clearness \Clear"ness\, n.
The quality or state of being clear.
Syn: {Clearness}, {Perspicuity}.
Usage: Clearness has reference to our ideas, and springs from
a distinct conception of the subject under
consideration. Perspicuity has reference to the mode
of expressing our ideas and belongs essentially to
style. Hence we speak of a writer as having clear
ideas, a clear arrangement, and perspicuous
phraseology. We do at times speak of a person's having
great clearness of style; but in such cases we are
usually thinking of the clearness of his ideas as
manifested in language. "Whenever men think clearly,
and are thoroughly interested, they express themselves
with perspicuity and force." --Robertson.
