What does 학 mean? What does 과 mean? I am a scientist, so I am wondering what these individual syllables mean in the word for science.
科學 (과학) - field of study, subject+learning, division +-ology. So, the specialty in which you pursue rigorous information. Of course, in many East Asian languages plurality is not explicitly specified unless it's absolutely necessary to communicating the intended meaning, so it's like the "fields of learning" and rigor has taken on an increasing value and implication.
