What is the meaning of Korean '정' in English?

um ano atrás
The concept of '정' in Korean seems to have no equivalent in English and is often referred to as one of the most difficult cultural concepts for foreigners to understand. I've had trouble explaining to non-Korean speakers myself. If you had to choose 1 or 2 words to describe it in English, how could you do that? And, if you had to give examples of what means in the culture and daily life, how could you do that as well?
