Sweet, what's the question though??
What book are you referring to in the question?
Answer:
The definition of circum means around or about.
Explanation:
prefix with the meaning “round about, around,” found in Latin loanwords, especially derivatives of verbs that had the general senses “to encompass or surround” (circumference; circumjacent; circumstance) or “to go around” by the means or in the manner specified by the verb (circumnavigate; circumscribe)
