Here are a few ways "whereas" is used at the beginning of a sentence:
* Contrasting facts or ideas:
> "The first painting is vibrant and colorful, whereas the second one is muted and somber."
* Highlighting differences between two things:
> "The north side of the mountain receives plenty of sunshine, whereas the south side remains in shade for most of the day."
* Introducing a legal or formal statement:
> "Whereas the parties have reached an agreement..." (This is often used in legal documents.)
Important points to remember:
* "Whereas" is formal and less common in casual conversation.
* The sentence following "whereas" should clearly contrast with the previous statement.
* Avoid using "whereas" to simply introduce a new topic. It should always be used to highlight a contrast or difference.
Here's an example of how "whereas" might be used incorrectly:
> "The weather is lovely today. Whereas I'm going to the grocery store later."
This sentence is grammatically correct, but "whereas" doesn't make sense because there's no contrast between the weather being lovely and going to the grocery store.
In conclusion, "whereas" is a powerful word to use at the beginning of a sentence when you want to create a clear contrast or opposition between two ideas.
