THE SIMPLE SENTENCE.
§ 110. In every complete thought there are at least two ideas (or notions) and a certain connexion between them. In the boy is going the two ideas are represented by the boy called the Subject, and going called the Predicate; and is shows the connexion between them. The nature of the connexion is different in each of the four kinds of sentences.
§ 111. The Simple Sentence in its Shortest Forms.
1. Subject, Predicate, and connexion may be all expressed by one word. Thus: tĭmĭō I-am-afraid, ī go (Sing.), grandĭnăt it-hails.
2. Subject may be expressed by one word, and Predicate and connexion by another word. Thus: ăvĭs vŏlăt the-bird is flying or flies.
3. Subject may be expressed by one word, and Predicate by another word, connexion being left to be understood from the context: victī hostēs the enemy (are) conquered, rāra avis the bird (is) scarce. This is almost entirely confined to Statements where the Verb (if inserted) would be est or sunt; and where the Predicate is an Adjective or Participle.
4. The Subject and Predicate may be expressed by separate words, and connexion by a part of the Verb sum. Thus: victī sunt hostēs the enemy are (or have been) conquered, Mārcŭs sĭt fēlīx may Marcus be happy.
