Step 1: Break the Latin term into parts.
Jus means law or right, and Soli comes from solum, meaning soil or land.
Step 2: Eliminate the other meanings.
Implied jurisdiction and opinion of law do not match this word breakdown, and right of blood is actually the opposite principle, known as Jus Sanguinis.
Step 3: Confirm the correct translation.
Jus Soli literally means right of the soil, the principle under which citizenship is granted based on the place of birth.
\[ \boxed{\text{Right of soil}} \]
