I, Nathan Carr Fullerton, have noticed one odd thing several times in the write ups of non native speakers that they often try complex compound sentences in their write ups and many times they use them incorrectly, which make their write-ups a thing for laughing.

With an aim to help non native speakers, I, Nathan Carr Fullerton, have decided to let you know about complex compound sentences that would for sure help you in writing.

Complex Compound Sentence:  

A compound complex sentence has features of complex as well as compound sentences both. A compound-complex sentence has two or more independent clauses and one or more dependant clauses. Since compound-complex sentences are longer than other normal sentences, you should be very much careful about putting punctuation sign in them.
