Summary: When studying root words, there are often spelling variants to a primary root word. The root word *ced*: "go," for instance, present in the words pre[*ced*]e and re[*ced*]e, has variant spellings of *cess* and *ceed*. Examples pro[*ceed*]ing from these variant spellings, all of which mean "go" as well, are ex[*cess*] and ex[*ceed*].
