Synonyms: common, ordinary, familiar
These adjectives describe what is generally known or frequently encountered. Common applies to what takes place often, is widely used, or is well known: The botanist studied the common dandelion. The term also implies coarseness or a lack of distinction: My wallet was stolen by a common thief. Ordinary describes something usual that is indistinguishable from others, sometimes derogatorily: "His neighbors were all climbing into their cars and trucks and heading off to work as if nothing miraculous had happened and this were just another ordinary day" (Steve Yarbrough).
Familiar applies to what is well known or quickly recognized: Most children can recite familiar nursery rhymes. See Also Synonyms at general.
