So, you know how sometimes when you talk to someone, you might use different words or language based on who you're talking to or where you are? That's called articulation!
In sociology, articulation means how people use language and words to show their social status or position in society. For example, someone who is wealthy might use fancy or academic language to make themselves seem more educated, while someone with a lower income might use more everyday language.
Articulation can also refer to how people use language to express their identity or belonging to a certain group. For example, someone might use slang or a regional dialect to show that they're part of a particular cultural group.
So basically, articulation is all about how people use words to show who they are and where they fit in society.
