Sentence can be defined as a group of one or more
words. On the other hand, sentence structure is
understood as the way basic grammatical elements (a
subject, predicate, and sometimes direct or indirect
objects) of a sentence are combined. The rules for how
a sentence is constructed are simple. These include the
necessity for a subject, predicate, and object (in that
order) in every sentence. Beyond that, we can also add
elements like prepositions and conjunctions. In
English, for example, sentences can be classified as
simple, complex and compound. That being said, check
the answer that provides the correct information about
the types of sentence structure in English.
