2. number - whether it is singular or plural
3. tense - past, present or future, and within each of these, whether the verb is simple, perfect or progressive
4. voice - if the subject is active or passive
5. mood - if the sentence is indicative (simple statement of fact), subjunctive (if it depends on conditions or something else to act) or imperative (a command)
