I want to know the answer to the following question:
The interjection "O" has been replaced by which more common and preferred word in English?
All the background I'm provided with is that "The names of the days of the week and the names of the months are also capitalised, as are the first-person pronoun "I" and the interjection "O" (although the latter is uncommon in modern usage, with "oh" being preferred).". Is that enough to answer the question?
