Many of the principles of syntax have been illustrated in the earlier part of this book, but a more complete statement of its laws will follow.
We have already learned that:
1. A sentence is an expression of a thought by means of words.
2. Sentences are either oral or written.
3. A thought may be expressed as: (a) A statement.
(6) A question.
(c) A command or an entreaty.
(d) An exclamation.
In whatever form a sentence may appear it must always contain a subject and a predicate.
The subject or the predicate may be understood.
