When one talks about structure, the image that comes to mind is a frame or shape of a building etc. But in the social field, the word structure, refers to a different thing. Let us examine such a framework called the caste structure. For example, the caste system in India has a definite structure where the Brahmins are at the top enjoying a priestly role, in the traditional sense, and the Shudras are at the bottom toiling over land, etc. followed by Kashtriya and Vaishya with the fourth rung taken up by the Shudras and lastly, the untouchables having the most marginalized positions.
