Compound statements:
Many propositions are composites that are, composed of sub propositions and various connectives discussed subsequently. Such composite propositions are called compound propositions.
A proposition is said to be primitive if it cannot be broken down into simpler propositions, that is, if it is not composite.
Example 2 : Consider, for example following sentences.

1. “The sun is shining today and it is colder than yesterday”

2. 
   “Sita is intelligent and she studies every night.”
   

Also the propositions in Example 1 are primitive propositions.
