I actually missed the first class in which this was discussed. Here is a list of professions we’ve encountered along the way and with an example, context-dependent sentence that amounts to saying someone (for which the context is clear if not defined here) is that profession. This will be useful for drilling down when to use 이에요 or 예요. In the case of this basic “is” verb, it conjugates to the noun.

직업 (한글) Profession Basic Context-Dependent Example Sentence
