◙ Interjections: -
An interjection is a word that is used to show a reaction or the way you feel about something.
E.g.      Hi! Hello! Wow! Really! How sad! Oh my god! Gosh! Never! How dare you! Hurray! Oh! Ah! Ouch! No way! Never!

◙ Word order: -
We have learnt all the parts of speech. So now we should be comfortable with sentences. Isn’t it?

Identify the correct sentence from the following sentences: -
Raj market went to.
Sonia playing a ball with.
Veer is shouting loudly.
Anita clothes was washing.

• Looking at these sentences, we come to know that knowing the parts of speech is not enough to speak English. Just like knowing the algebra figure is not enough. To solve the sums one must know the correct formula.

Every sentence comprises a subject, about which we are talking, and a predicate which gives information about the subject.
E.g.      Raj is playing the guitar.
Raj – subject, is playing guitar – predicate.
Rahul has gone to the theater.
Rahul – subject, has gone to the theatre – predicate.

In most cases the sentence always beings with the subject, followed by a word that indicates tense (when required), which again is followed by verb or noun. (STV/N)
E.g.      Rahul is crying.
S   T   V
Rita has a car
S   T    N
Now you know the subject is followed by the tense indicator which is followed by a verb or noun. It so happens that sometimes the word after the subject does the work of the tense as well as the verb
E.g.      Smita sings well.
Smita – subject
Sings – verb + word indication the present tense as otherwise it would be “sang”. Now you know that a regular sentence construction formula is subject + tense indicate + verb/noun.
When you are saying something that happens on a regular basis, or is factual then you normally refer to such a sentence. And when you are describing something that is happening continuously then you say Smita is singing or was singing. Then you have a separate word which describes the tense, and a separate.
Word indicating the verb.
Some more examples: -
Arjun danced flexibly.
Sonia irritates me.
Raj dislikes her.
In all the above sentences you will see that the verb is placed right after the subject which is originally the place of the tense indicator. So those verbs are not only playing the role of verb but also of tense indicator past or present.
Now you must be thinking that6 every sentence must follow the formula explained. So let’s see how you would make this sentence.
E.g.      You are why crying?
Is this right?
The subject “you” is placed right in the beginning as per the rule, and the word indication tense is right after followed by the verb. So it should be right, isn’t it?

Questions have a different formula. They mostly being with “why, what, who, when, where.” Followed by the tense indicator, followed by the subject, followed by the verb or noun in maximum cases.
E.g.      why are you crying?
Why
Are – tense indicator (t)
You – subject (s)
Crying – verb (v)
E.g.      When will Raj come?
When
Will – tense indicator (t)
Raj – subject (s)
Come – verb (v)
So, the basic formula for questions (TSV/N) can be taken as reverses of the regular statement formula (STV/N)
