      Earliest common ancestor is great-grandparent. With same number intermediaries for both people.

      n^th cousin is how many “g’s” in the title of the earliest common ancestor. Grandparent == one “g” = first cousin. Two gs, second cousin, etc.

      “Removed” is the offset value, or the difference between how many intermediaries between the two parties and their earliest common ancestor.
