Common sense

Common sense is a basic ability to perceive, understand, and judge things, which is shared by ("common to") nearly all people and can reasonably be expected of nearly all people without any need for debate.

The everyday understanding of common sense is derived from philosophical discussion involving several European languages. Related terms in other languages include Latin sensus communis, Greek κοινὴ αἲσθησις (koinē aísthēsis), and French bon sens, but these are not straightforward translations in all contexts. Similarly in English, there are different shades of meaning, implying more or less education and wisdom: "good sense" is sometimes seen as equivalent to "common sense", and sometimes not.
