However, it's possible you're thinking of a word that *contains* "tol" as part of its root. Here are some possibilities:
* Tolerate: This word comes from the Latin "tolerare," which itself comes from "toler," meaning "to bear, to endure, to support."
* Toll: This word comes from the Old English "tol," meaning "a tax, a fee."
If you can provide more context about where you encountered the word "tol," I might be able to provide a more specific answer.
