Sentence Structure
A sentence makes complete sense because it is made up of a group of words that expresses a complete thought. Sentences always begin with a capital letter and end with a full stop. There is always a subject (containing a noun or noun phrase) and a predicate (containing a verb or a verb phrase). According to grammar rules a subject + predicate = sentence. There is always a main clause found in sentences.
A clause can either form part of the main sentence in the case of complex- compound sentences or be a complete sentence in itself.
A compound sentence has at least two independent clauses and are joined by conjunction such as ‘and’ or ‘but’.
A complex sentence has at least one independent and one dependent clause.
