Identify the adjunct in the given sentence-
Suddenly, it started to snow.
A) To snow
B) Suddenly
C) It
D) None of these

Hint: An adjunct refers to an adverb or a phrase that is used to modify a verb. Adjuncts do not hold greater importance in a sentence. Hence, they can be eliminated from a sentence without altering the grammatical sense or the meaning of that sentence.

Complete answer:
As given in the hint, adjuncts are generally formed with the help of the different kinds of adverbs.
Let’s look at the usage of adjuncts-
Example: The teacher wrote on the blackboard. Here, ‘on the blackboard’ is an adjunct representing an adverbial phrase. ‘On the blackboard’ can be removed from the sentence without altering the grammatical meaning of the sentence.
Also, we always use a comma after an adjunct if it is placed at the beginning of a sentence-
Example- While she was working, the boss took us for lunch.
In the given question- We know that ‘suddenly’ is the adjunct as it is placed at the beginning of the sentence and it can be removed from the sentence without changing the meaning of the sentence.
Now, let’s examine the given options-
Option a- ‘To snow’ is a to-infinitive verb that is placed after the main verb to modify the expression of the main verb. Hence, it is an incorrect option.
Option b- ‘Suddenly’ is an adjunct as it is an adverb that is used to modify the verb. Hence, it is the correct option.
Option c- ‘It’ is the subject of the sentence. Hence, it is an incorrect option.
So, the correct answer is “Option b”.

Note:
Keep in mind, adjuncts are not necessary for the formation of a sentence. Adjuncts act as extra information or detail that helps in describing the verb.
