Synonym Discussion of PLAIN

common, ordinary, plain, familiar, popular, vulgar mean generally met with and not in any way special, strange, or unusual. common implies usual everyday quality or frequency of occurrence <a common error> <lacked common honesty> and may additionally suggest inferiority or coarseness <common manners>. ordinary stresses conformance in quality or kind with the regular order of things <an ordinary pleasant summer day> <a very ordinary sort of man>. plain is likely to suggest homely simplicity <plain hard-working people>. familiar stresses the fact of being generally known and easily recognized <a familiar melody>. popular applies to what is accepted by or prevalent among people in general sometimes in contrast to upper classes or special groups <a writer of popular romances>. vulgar, otherwise similar to popular, is likely to carry derogatory connotations (as of inferiority or coarseness) <souvenirs designed to appeal to the vulgar taste>.

evident, manifest, patent, distinct, obvious, apparent, plain, clear mean readily perceived or apprehended. evident implies presence of visible signs that lead one to a definite conclusion <an evident fondness for sweets>. manifest implies an external display so evident that little or no inference is required <manifest hostility>. patent applies to a cause, effect, or significant feature that is clear and unmistakable once attention has been directed to it <patent defects>. distinct implies such sharpness of outline or definition that no unusual effort to see or hear or comprehend is required <a distinct refusal>. obvious implies such ease in discovering that it often suggests conspicuousness or little need for perspicacity in the observer <the obvious solution>. apparent is very close to evident except that it may imply more conscious exercise of inference <for no apparent reason>. plain suggests lack of intricacy, complexity, or elaboration <her feelings about him are plain>. clear implies an absence of anything that confuses the mind or obscures the pattern <a clear explanation>.

frank, candid, open, plain mean showing willingness to tell what one feels or thinks. frank stresses lack of shyness or secretiveness or of evasiveness from considerations of tact or expedience <frank discussions>. candid suggests expression marked by sincerity and honesty especially in offering unwelcome criticism or opinion <a candid appraisal>. open implies frankness but suggests more indiscretion than frank and less earnestness than candid <open in saying what they think>. plain suggests outspokenness and freedom from affectation or subtlety in expression <plain talk>.
