Structural Classification of English Sentences
Sentences can be divided into four classes from structural point of view as,
1. Simple Sentence
2. Compound Sentence
3. Complex Sentence
4. Compound-Complex (or Double Sentences)
1. Simple Sentence. A simple Sentence has only one Subject and one Predicate. It has only one Finite Verb; as,
(i) She went to market.
(ii) I shall attend the function.
(iii) The students have done their homework.
(iv) The sun sets in the west.
(v) Man is a social animal. (vi) Brevity is the soul of wit.
2. Compound Sentence. A compound sentence consists of two or more Co-ordinate clauses; as,
(i) I was tired and I rested.
(ii) I went to market and purchased a television.
(i) You tried hard but could not succeed.
(ii) We went to Lahore and visited Badshahi Mosque.
Note. All the clauses of a compound sentence are of the equal rank.
Sometimes the subject is omitted in the second coordinate clause as in sentences (ii) (iii) and (iv) above.
3. Complex sentence. A complex sentence consists of one Main clause and one or more Subordinate clause; as,
(i) I don’t know where he lives.
(ii) She went abroad after she had completed her graduation.
(iii) If you work hard you will pass.
(iv) He rested when he was tired.
Note. A complex sentence may have any or all the subordinate clauses, besides having one Principal or Main clause.
