1023. A SENTENCE is a thought expressed by means of a verb. The SUBJECT
is that which is spoken of. The PREDICATE is that which is said of the
subject.
1024. A SIMPLE SENTENCE is one which has only one subject and one
predicate.
Thus, #Rhodanus fluit#, _the Rhone flows_, is a simple sentence: the
subject is #Rhodanus# and the predicate is #fluit#.
1025. The sentence may be _declarative_, stating a fact, _exclamatory_,
crying out about something, _interrogative_, asking a question, or
_imperative_, giving a command.
