Why Sulphur and Not Sulfur?
Originally called Saratoga Springs (and sometimes referred to as Warm Springs), the town name as we know it today is Hot Sulphur Springs. So, why sulphur instead of sulfur?
The simple answer is that ‘sulphur’ is the British spelling of the word and ‘sulfur’ is the American spelling. Both forms of the word have been in use for many years. When the town was named in the late 1800s, it was likely more common to use the spelling ‘sulphur.’
