The document discusses the importance of understanding the purpose and reason for studying a subject like accountancy. It uses examples of a student's academic year and a businessman's business transactions to illustrate how language barriers could cause issues. For a student, not understanding the language of instruction could mean not being able to take notes, learn topics, or write exams, leading to poor grades. Similarly, a businessman would not be able to maintain business records without understanding the language, preventing him from knowing the results of his year-long efforts. The document argues that accountancy provides the language for recording business transactions, which is why it is important to study.
