Moreover: an addition to what is said, not a contradiction. "He eats pork. Moreover, he absolutely loves it." .. But: You provide a contradiction, or a negative aspect to what comes before: "He eats pork, but he doesn't like it." Though is used in the same way as 'but'. "He eats pork though he doesn't like it." However, there is a subtle difference. 'Though' refers to an obstacle that can be overcome, whereas 'but' often refers to something that can't be overcome.

It is normally used to replace 'on' in many contexts. However, it is extremely formal, and may be one of the words that is going out of use. We certainly used to use it a lot more than we do now.

Here's an example: 1. We could invite Mary, but she talks a lot. 2. We could invite Mary though she talks a lot. 3. We could invite Mary. Moreover, she talks a lot. In #1 Mary's talking is a strong reason not to invite her. In #2 Mary's talking is a mild reason not to invite her. In #3 the fact that Mary talks is just extra information.

"Moreover," "but," and "though" are transitional words or adverbs used to convey different relationships and connections between ideas in a sentence or between sentences. Here's an explanation of their meanings and usage: Moreover: "Moreover" is used to introduce an additional point or idea that supports or reinforces what has already been stated. It indicates that the information being added is of the same kind or category as the preceding information. It emphasizes the cumulative effect of the points being made. For example: "I enjoy reading books. Moreover, I find them to be a great source of inspiration." In this example, "moreover" is used to introduce an additional idea that strengthens the statement about enjoying reading books. But: "But" is a conjunction used to introduce a contrasting or contradictory idea. It indicates a shift or opposition in thought, often presenting an alternative viewpoint or presenting an unexpected result. It is used to show a conflict or contradiction between two statements or ideas. For example: "I wanted to go to the party, but I had to stay home and finish my work." In this example, "but" introduces a conflicting idea, indicating that the desire to attend the party is in opposition to the necessity of completing work. Though: "Though" is a conjunction or adverb used to introduce a concessive or contrasting idea. It shows a contrast or concession to a previous statement, often expressing a surprising or unexpected outcome. It is used to indicate an exception or to introduce a contrary point. For example: "She studied hard for the exam, but she didn't get a good grade, though." In this example, "though" introduces a surprising outcome, suggesting that despite studying hard, the person did not achieve a good grade. In summary, "moreover" adds additional information or support to the preceding idea, "but" introduces a contrasting or conflicting idea, and "though" introduces a surprising or contrary point.
