<span>A </span>simple sentence<span> contains the basic element
that make a sentence and that is a subject and a predicate. The sentence must
one independent clause and expresses one idea. Compound sentences other hand contains
two ideas. In the sentence: </span>My sister works with clay; she
molds and paints it. It is a compound sentence since there are two ideas, that
is, two subject ‘sister’ and ‘she (basically still the sister)’ and two
predicates ‘works with clay’ and ‘molds and paints it’.
