The subject is the argument that precedes the verb. In finite clauses it shows agreement with the verb and appears in nominative Case. Finite clauses always have visible subjects, even if there is no semantic motivation for it. In these cases the subject is an expletive element, e.g. it in It is important to finish with the project today. Non-finite clauses can have an unpronounced subject, if they have a visible subject it appears in accusative Case.
