Colloquialism refers to words, phrases or expressions that are used in informal conversations and settings and that are commonly known and used in a region or country. In American English, examples of this type of speech are contracted words like <em>gonna, wanna </em>and<em> Y'all</em>, and certain terms like <em>bamboozle, </em><em>OK, </em>which denotes approval or acknowledgment, and<em> </em><em>folk's</em>, which is a more informal and friendly way to address people in general, or one's parents or family's members.
