This is a good example of a way the Chinese language is underrated. I had not seen the word "监护人" before, but I had seen "监" many times and so I knew the word had something to do with supervising.

Turns out I guessed correctly: 护卫着 is like "security guard", 监护人 is like "guardian (of a child)"

Yes many nouns can be guessed or at the very least communicated approximately in Chinese (比如说”火山”). The phonetic translations (loanwords) are nice as well.

黑客 is the best. It's a phonetic translation *and* it has a cool literal meaning!
