Tautology Concept


The term “Tautology” has been recently included in CBSE PSA exams and is quite new concept for most of the students. In reality, it is a process of the use of words or phrases within a single statement in a speech and bookish structure. It is a statement that is true at all the times and it does not require theory or proof to decide its truth. Its example is found in every language and culture.

This new concept is explained in a simple language in DISHA Publication’s book named”Crack CBSE PSA 2015”. Get it from the publishing house either online or offline and build up your concept about this topic.
