What does common mean?
"Common" is one of English's most versatile everyday words. As an adjective, it chiefly describes something that occurs frequently or is widespread — a common cold, a common surname — or something shared jointly by many people, as in common property, common interests, or finding common ground. A second, older sense marks things as ordinary rather than distinguished: the common people, common folk. This sense survives most visibly in institutional names like the House of Commons and in phrases such as "commoner," though when applied to individuals' manners it can sound condescending and is best avoided. As a noun, "common" refers to land open to public use — a village green where residents once grazed animals — giving us the phrase "common land." The word derives from Latin "communis," meaning shared by all, making it a close relative of "community," "communal," and "communicate." Its central idea of sharedness underlies both its literal and figurative uses today.
Occurring frequently, widely found, or shared by many people or things; also, belonging equally to a whole group.
"Migraines are more common in women than in men."
When used of people or behaviour, an older pejorative sense (vulgar, low-class) may be implied, particularly in British English.
A piece of open land for public use, especially in a village or town; also, the common people regarded as a class (usually "the commons").
"We took the dog for a walk across the common."
The plural "commons" appears chiefly in "the House of Commons" and in historical or legal references to common land.
Used mainly in set expressions such as "the House of Commons" or to refer to parcels of public common land; rarely used outside these contexts.
"The bill passed easily through the Commons before moving to the House of Lords."
In medieval England, "the commons" meant the ordinary people as opposed to the nobility and clergy — which is why the lower house of the British Parliament is still called the House of Commons.

Etymology of common
The word "common" entered Middle English from Old French "comun," itself inherited from Latin "communis," meaning "shared by all or many; public." The Latin root gave rise to a whole family of related words, including "community," "communal," and "communicate," all built on the same notion of shared participation. In medieval England, "the commons" came to denote both common land and the body of ordinary people below the nobility and clergy, a sense preserved in the House of Commons.

How common is actually used
As an adjective describing people or manners, "common" can carry a dated and potentially derogatory connotation of being vulgar or low-class, especially in British English — use care in that register. The neutral, dominant modern use is simply "frequent" or "widespread." The plural form "commons" appears mainly in fixed expressions such as the House of Commons or public commons land.
Easily confused with common
