– Open; frank; unreserved; artless; plain; sincere; candid; fair;
noble; generous.
– Ingenuous, Open, Frank. One who is open speaks out at once what
is uppermost in his mind; one who is frank does it from a natural
boldness, or dislike of self-restraint; one who is ingenuous is
actuated by a native simplicity and artlessness, which make him
willing to confess faults, and make known his sentiments without
reserve. See Candid.
