Definition of the word oh

The word "oh" is one of the most commonly used interjections in the English language. Its origin dates back to Old English, where it was spelled "æh" or "ah". This expression was used to convey surprise, disappointment, or shock. Over time, its spelling evolved to "oh" and its use expanded to include a wide range of emotions, from mild surprise to sudden comprehension. In the 16th century, the word "oh" became a distinct interjection in its own right, separate from other expressions of surprise like "alas" or "ah". Its popularity grew throughout the 17th and 18th centuries, with the rise of emotive literature and the development of colloquial language. Today, "oh" is a fundamental part of everyday language, used by people of all ages and backgrounds to express a wide range of emotions and reactions.
