Subject & predicate is one of the most important & basic topic in English Grammar.
There are some key points to remember:
1. Usually in a regular sentence order is:
Subject at the beginning, followed by the predicate.
Exception:
Sometimes for emphasis, predicate comes at the beginning of the sentence, followed by the subject.
Example:
On the hill stood a tall tree.
Here,
- A tall tree - subject.
- On the hill - predicate.
2. For interrogative & exclamatory sentences the order is:
Predicate - subject - predicate
Examples:
- What are you wearing?
- How beautiful she is!
Here, 'you, she' are the subjects, rest all is the predicate.
3. Imperative sentences:
Subject may be implied.
Example:
Sit down.
Here, the subject you is implied.
Hence the sentence is: You sit down.
