The spelling of the phrase "stopt oneself" is a reminder of how the English language has evolved over time. The word "stopt" is an archaic spelling of "stopped", and both are pronounced the same way: /stɑpt/. Similarly, "oneself" is pronounced as /ˌwʌnˈsɛlf/. The use of archaic spellings in modern English may seem strange, but it is a reflection of the language's rich history and the influence of different cultures on it. In the end, the spelling of a word may change, but its pronunciation remains the same.
