Answer:
Colloquialism
Step-by-step explanation:
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 gonna, wanna and Y'all, and certain terms like bamboozle, OK, which denotes approval or acknowledgment, and folk's, which is a more informal and friendly way to address people in general, or one's parents or family's members.
