# Where does the word root comes from?

Where comes the word root when talking about the points when a polynomial gets the value $$0$$?

• Latin radix (and the Arabic word it translated, used already by al-Khwarizmi) means root or base, and was originally applied to solutions to $x^n=a$, where $x$ is the "base" of $a$. The use then apparently spread to other polynomials, see Why is the radical symbol √ called “radical”? Oct 8 '20 at 23:11
