English: Learn English: Interjection

Interjection

Interjection is used to express emotions or feelings (Joy, Sorrow, Wonder, Fear, Anger etc). It itself is not meaningful but after reading full sentence, we can easily understand for what it has been used. (Interjections are not specific to English only. Many are those which are same in other languages also)
Exclamation mark is used with interjection and after this mark, the word is written with Capital letter
Examples:
Hurrah! I got first position in Science Subjects.
Alas! Our father passed away last night.
Ah, Aha, Yahoo, Wow etc are examples of interjections.

Sentence Structure:
Now we are in a position to understand the structure of a sentence.
A basic sentence has three parts i.e.
Who + What + By Whom (Subject + Verb + Object)
Subject means any noun or pronoun that is performing the action.
Verb is the action and Object is also some noun or pronoun but the one on whom the action is being performed.
Examples:
He plucked a flower.
They play cricket.
Complex Sentence Structure:
Now if we want to use all parts of speech described above in a single sentence, the sentence structure will become a little tough. See the below structure:
Interjection + Subject + Verb + Preposition + Adjective + Object + Adverb + Conjunction + 2nd Sentence.
Example:
Hurrah! I have qualified for this match very successfully and I am much glad.
Aha! It has started raining in our deserted area heavily and children are enjoying outside.
(Adjective and adverb can be used somewhere else according to the requirement)
(This is an average sentence, many exceptions are still there)
All parts of a sentence can be omitted but verb is necessary to make sense.
So it is clear that how different parts of speech can be used altogether.
