Negation exception!!!!!

In French generally the negation of any positive sentence is composed by adding ne before the main verb and adding pas after the main verb. However there is the flexibility in French that we can even avoid the use of ne before the verb while speaking but which is obligatory while writing.

For eg>je comprends.(za compran) literally means I understand is the positive sentence. As the grammar rule its negation will becomes je ne comprends pas(za na compran pa) literally means I donot understand. However the use of ne could be avoid while speaking and just can use je comprends pas(za compran pa) literally means I donot understand too. This format of speaking negation is widely used by French Speaker and accepted too.
