&hand; This word and its derivatives are often written with c instead of k in the first syllable, -- sceptic, sceptical, scepticism, etc. Dr. Johnson, struck with the extraordinary irregularity of giving c its hard sound before e, altered the spelling, and his example has been followed by most of the lexicographers who have succeeded him; yet the prevalent practice among English writers and printers is in favor of the other mode. In the United States this practice is reversed, a large and increasing majority of educated persons preferring the orthography which is most in accordance with etymology and analogy. Syn. -- Infidel; unbeliever; doubter. -- See Infidel.

One who is yet undecided as to what is true; one who is looking or inquiring for what is true; an inquirer after facts or reasons.
