What is learning? (and how do you know when you've learnt)

Alright...So, I'm in the midst of learning a new language BUT let's dig deeper... that still does not answer, what on earth is learning and how do we know if we have learnt? 

I believe learning is an epistemic action that involves social relations. It is the relationship between the social world and individuals. It is a social creation. What makes it intriguing is that individuals create learning yet learning shapes and creates individuals. When I get that, "Ah, Ha! I know something new that I didn't before" moment happens, I've realized it is because I am habitually accepting ideas that appear as absolute truths. These ideas come from religion, professors, parents and the mass media. It is not that I passively accept knowledge, I acknowledge counter-ideologies and perspectives but I believe knowledge is a social construction. It is mesmerizing to think about why and how I know what I know. The contemporary world emphasizes the individual and convinces us that we live in a world where neutrality exists. I have begun to realize that relations of power, history and a process of socialization shape my beliefs and ideas. I did not consciously construct my worldview myself. My ideological framework has been fabricated over the span of my lifetime.
