Answer:

strong negative linear

Explanation:

Given two random variables X and Y, the correlation coefficient measures the linear relationship of X and Y. When the correlation coefficient is exactly +1, we have a perfect positive linear relationship and when the correlation coefficient is exactly -1, we have a perfect negative linear relationship. The lowest value the correlation coefficient can take is -1, and the highest value the correlation coefficient can take is +1. Therefore, when the correlation coefficient is -0.90 we have a strong negative linear relationship.

Elan Coil [88]

Answer: Hegemonic language.

The concept of hegemony was developed by Antonio Gramsci and it refers to a geopolitical method of indirect political dominance.

In the context of language, a hegemonic language can cause linguistic dominance, by asserting itself above all other languages. It can also reinforce power dynamics that have already been established by the culture’s institutions. As such, it can be a form of embodied cultural capital.
