Once you understand the two patterns, you can write any kind of sentence you like without the slightest fear of going astray. Love is blind. The cat scratched Sally. John gave his mother flowers. The teacher considered him a good student.
Every English sentence contains a basic statement.
It may stand alone as one short sentence as in the examples above, or it may be buried inside a longer sentence. This sentence is a basic statement with a string of details added to it. Delay, of course, is the secret weapon of the periodic sentence. In this sentence, additional details are added before and after the basic statement. Once you have learned to recognize and use the two major sentence patterns, you can forget about adhering to them strickly.
