The study of grammar may focus on the rules of the English language and provides students with the skills to correctly write and speak English. Scholars may be able to apply this knowledge to language acquisition for non-native speakers.

Master-level studies involve specialized study in a field of research or an area of professional practice. Earning a master’s degree demonstrates a higher level of mastery of the subject.
Earning a master’s degree can take anywhere from a year to three or four years. Before you can graduate, you usually must write and defend a thesis, a long paper that is the culmination of your specialized research.
