What is Ought To?

Ought to is a verb. It is used in sentences relating to something they desired to happen but didn’t. They ought to also be modal verbs describing the subject’s duty or correctness. 

The phrase ought to is always followed by another verb. Initially, the phrase ought to be brought to life in the 12th century as an auxiliary verb, in the 13th century as a verb, and in 1678 as a noun.  

There are many definitions for the word OUGHT, starting from the term used to express obligation, recommend ability, logical outcomes, and subjective expectation.

And each usage means different; the first two meanings come from the old English dictionary, defining transitive verbs like possess and owe. Secondly, the ought to phrase defines the duty or obligation of the action in the recent English dictionary.

For a better understanding, below is the example for Ought to the phrase:

  1. I ought to finish my work before 9 pm. 

This means it is my duty or obligation to complete my work before the clock hits 9 pm. 

  1. I ought to get up early to stay fit as a fiddle. 

The above sentence defines that I am talking about the things that I desire to do.

Meanwhile, the Need to phrase is both a verb and modal verb that defines the necessity or requirement of the action that has to be done without any pretence. Frequently, a need to be used in a sentence with a negative impact.

The ‘Need to’ phrase has been used since the origin of the English language, and there is no other change to the words yet. 

For instance, I need to find a house soon for my family. The sentence describes the necessity or importance of buying a house for her family to survive.
