Key Differences

Discipline, in the academic sense, often refers to a broader field of study or knowledge, like "biology" or "history." Within such disciplines, numerous specialized areas and topics can be studied. Subject, on the other hand, can be a more specific area within a discipline or simply a topic under discussion, like "cellular biology" within biology or "World War II" within history.
Additionally, the term "discipline" carries with it connotations of regulation, control, and training. For instance, one might discipline oneself to adhere to a routine or discipline a child for misbehaving. The word "subject," aside from its academic connotation, can also mean someone or something that undergoes a particular action or process.
Within the academic world, many subjects come together to form a discipline. For instance, the discipline of "psychology" encompasses subjects such as "child psychology," "clinical psychology," and "neuropsychology," among others. Subjects delve into more specific areas or topics within the broader scope of a discipline.
In general conversation, when someone mentions their discipline, they often refer to their overarching field of study or expertise. However, when they discuss a subject, they could be talking about a particular topic they are studying, discussing, or teaching. Both terms, while often used interchangeably, have nuanced differences in meaning and context.
