Sentence combining is a technique used to improve writing by joining two or more simple sentences into a more complex and interesting sentence. This can be achieved through the use of conjunctions, relative pronouns, participles, and other grammatical devices.
For example:
* Simple sentences: The dog barked. The cat hissed.
* Combined sentence: The dog barked, and the cat hissed.
Sentence combining can make writing more concise, sophisticated, and engaging for the reader.
