English

A compound noun is a noun formed by combination of two or more nouns to create a new meaning. For example, when we combine two nouns 'air' and 'plane' it forms a compound noun 'airplane'. Other examples are:

• Bookshop: book and shop
• Rainbow: rain and bow
• Sunflower: sun and flower

Misidentification of the subject or predicate, and incorrect verb agreement with the subject are the common errors in the topic. Sentence fragments, which are incomplete sentences missing a subject or predicate, can also lead to errors in this area of English grammar.

Largely, there are three types of subject and predicate in English grammar. They are: 

·       Simple subject and predicate

·       Compound subject and predicate

·       Complete subject and predicate

A sentence can have more than one subject and predicate. It can be a compound subject/predicate. In other case it can be two completely different subjects performing various actions in the same context. Sentences with compound subjects have more than one simple subject but may have only one predicate. Sentences with compound predicates have more than one simple predicate but may have only one subject.

The predicate tells what the subject does or is. It includes the verb and any other words that complete the meaning of the sentence. It is the latter part of the sentence that gives information about the subject or the action that is being performed.

The subject, includes word or group of words that tell what or who the sentence is about. They can be noun or pronoun. In other words, subject is a person or thing that is being considered, shown or talked about in the sentence. It is the main focus of the sentence.

Nouns are important because they talk about people, place, things or ideas. Nouns acts as foundation in a sentence by acting as subject, verb and more. Without a noun in a sentence, it would look vague and incomplete. Nouns gives identification, builds sentence, acts as subject, and provides clarity.

• Countable nouns have both singular and plural forms, whereas, uncountable nouns does not have singular or plural forms.
