Mastering Superlative Degrees of Comparison & Infinitive Verbs: A Complete Grammar Guide

In English grammar, understanding how to compare items accurately and how to structure verbs is fundamental to clear communication. In this guide, we will break down two key grammatical concepts: Superlative Degrees of Comparison and Infinitive Verbs.

Part 1: Understanding Superlatives in English

We use superlative adjectives when answering questions about extreme degree—identifying a particular person or thing that stands at the very top or bottom of a group.

When pointing out a top item among many, we frequently use the structure "one of the" before the superlative adjective. Crucially, the noun following this structure must always be plural (e.g., "one of the students", "one of the posts").

We use the superlatives in answers to any kind of general or specific questions. Let us know the way how to identify a particular person or thing out of so many which are in the top position? In some cases we use the expression "one of the" before the superlative and we also use the noun in plural after the superlative adjective, i.e., "students", "posts". Some of the examples are:

Examples of Superlative Sentences

1. Hazel is the fastest runner and the tallest athlete in his school.
   
   
2. He was not the greatest of all painters, but he was one of the greatest painters.
   
   
3. Russia is one of the most technologically advanced countries in the world.
   
   
4. One of the best singers of the team arrives today.
   
   
5. None of the perfect disciples was ready to preach to the people in this city.
   
   
6. Isn't lemon one of the best fruits we saw in our country?
   
   
7. This is one of the most expensive cars on the market.
   
   
8. Wasn't Ranasingh one of the most successful bowlers on the last foreign tour?

Detailed Guide on Forming Superlative Adjectives

To form superlatives correctly, follow these core rules based on word length:

1. One-Syllable Adjectives

Add "-est" to the end of the adjective:

• Fast becomes Fastest
  
  
• Tall  becomes Tallest
• Short becomes Shortest

2. Two or More Syllable Adjectives

Place "most" or "least" before the adjective:

• Expensive becomes Most expensive
  
  
• Beautiful becomes Most beautiful
  
  
• Important becomes Most important
  
  

3. Irregular Superlatives

These forms change completely and do not follow standard patterns:

• Good becomes Best
  
  
• Bad becomes Worst
  
  
• Far becomes Farthest / Furthest
  
  
• Little becomes Least
  
  

Common Superlative Mistakes to Avoid

• Double Superlatives: Never combine "most" with an "-est" word. Write "the fastest runner", not "the most fastest runner".
  
  
• The Definite Article ("The"): Always include "the" before a superlative adjective because it points to a specific top item (e.g., "She is the smartest student in class").
  
  
• Plural Nouns After "One of the": Always pair "one of the" with a plural noun (e.g., "one of the best cities", not "one of the best city").
• 
  

Then up to this part, we studied about degrees of comparison. Now let us study about infinitives. Then what is an infinitive?

Part 2: What is an Infinitive Verb?

Now that we have covered degrees of comparison, let us move on to Infinitives.

An Infinitive is the base form of a verb, almost always preceded by the word "to" (e.g., to eat, to run, to learn). While it originates from a verb, an infinitive can function as a noun, an adjective, or an adverb within a sentence.

Part 3: Infinitive Placement (Verb + Infinitive)

In sentence construction, infinitives frequently follow a main conjugated verb. In these structures, the primary verb sets the main action or tense, while the infinitive expresses the purpose, goal, or direction.

Placement Examples

Main Sentence Example:

"She decided to study all night."

• 1st Verb (Conjugated Action): decided
  
  
• 2nd Verb (Infinitive Goal): to study
  
  

Additional Examples:

1. I wanted to help her.
   
   
2. He tried to run.
   
   
3. I want to go.
   
   
4. They told us to learn.
   
   
5. He tries to help.
   
   

Examples of INCORRECT Placement:

• I to eat like. Correct: I like to eat.
  
  
• He wants runs. Correct: He wants to run.
  
  
• I to go want. Correct: I want to go.

What is an INFINITIVE?

An Infinitive is the base form of a verb, almost always preceded by the word "TO".

As a Noun, "to eat".  Function:  Direct object of the verb "want".  Example:  I want "to eat".

As an Adjective, "to read".  As an adjective:  Function: Describes the books.  Example:  She has books to read.

As an Adverb, "to help".  As an adverb, Function:  Explains the purpose "why they came".  Example, They came to help.

Special Cases:  Split infinitive (eg. to quickly run).  Bare infinitive (e.g., must on go).

Grammatical Functions of Infinitives

• As a Noun: Direct object of a verb.
  
  
  • Example: I want to eat. (Function: Answers "what" I want)
    
    
• As an Adjective: Modifies a noun.
  
  
  • Example: She has books to read. (Function: Describes the books)
    
    
• As an Adverb: Explains purpose or cause.
  
  
  • Example: They came to help. (Function: Explains "why" they came)

An infinitive is a simple sentence which can have more than one verb but that verb must be in a modified form. If we use the preposition "to" before any present form of verb, the combination is known as infinitive.

Part 4: Deep-Dive into Types of Infinitives

While most infinitives follow the standard "To + Base Verb" pattern, native speakers use several key variations depending on sentence structure:

A. Full Infinitive (To + Verb)

Used after specific main verbs, adjectives, or to express purpose:

• I plan to visit Chennai next month.
  
  
• It is hard to master a new language.
  
  

B. Bare Infinitive (Verb without "To")

Used directly after modal auxiliary verbs (can, could, may, might, must, shall, should, will, would) or perception verbs (see, hear, feel):

• She can speak three languages fluently. (Not: She can to speak)
  
  
• They must leave early. (Not: They must to leave)
  
  

C. Split Infinitives

A split infinitive occurs when an adverb is placed directly between "to" and the base verb:

• To boldly go where no one has gone before.
  
  
• He promised to carefully review the document.
  
  

D. Negative Infinitives

To make an infinitive negative, place "not" directly before "to":

• She decided not to go to the party.
  
  
• Please try not to make noise.

  • 1st Verb, Action: decided
    
    
  • 2nd Verb, Infinitive: to study
    
    
  • Rule Check: 1st → 2nd ? YES.
    
    

Additional Examples of Placement

1. Detailed Guide on Forming Superlative Adjectives:

How to Form Superlative Adjectives correctly:

1. One-Syllable Adjectives: Add "-est" to the end of the word.
   
   
   • Fast becomes Fastest
     
     
   • Tall becomes Tallest
     
     
   • Short becomes Shortest
     
     
2. Two or More Syllable Adjectives: Place "most" or "least" before the adjective.
   
   
   • Expensive becomes Most expensive
     
     
   • Beautiful becomes Most beautiful
     
     
   • Important becomes Most important
     
     
3. Irregular Superlatives: These forms change completely and do not follow standard patterns:
   
   
   • Good becomes Best
     
     
   • Bad becomes Worst
     
     
   • Far becomes Farthest / Furthest
     
     
   • Little becomes Least
     
     

Common Superlative Mistakes to Avoid:

• Double Superlatives: Never combine "most" with an "-est" word (e.g., say "the fastest runner", not "the most fastest runner").
  
  
• The Definite Article ("The"): Always include "the" before a superlative adjective because you are referring to a single, specific top item (e.g., "She is the smartest student in class").

Summary Box

• Summary: The FIRST verb sets the action; the INFINITIVE is the goal or purpose (2nd).

Infinitive Verb Concept:

Infinitives After Verbs:

The infinitive can follow a first verb, either immediately or separated by an object.  1st verb is CONJUGATED, examples wants, tries, likes, needs, tells.  The 2nd verb is INFINITIVE (to + base form verb), examples to study, to run, to go, to help, to play.

Example RIGHT sentences.

1.  I want to go.

2.  I want to learn.

3.  They told us to learn.

4.  I want to learn.

5.  He tries to help.

Example WRONG sentences:

1.  I to eat like.

2.  He wants runs.

3.  I to go want.

2. Deep-Dive into the Types of Infinitives:  

While most infinitives follow the standard "To + Base Verb" pattern, native speakers use several variations depending on the context:

A. Full Infinitive (To + Verb)

Used after specific main verbs, adjectives, or to state a purpose:

• I plan to visit Chennai next month.
  
  
• It is hard to master a new language.
  
  

B. Bare Infinitive (Verb without "To")

Used directly after modal auxiliary verbs (can, could, may, might, must, shall, should, will, would) or perception verbs (see, hear, feel):

• She can speak three languages fluently. (Not: She can to speak)
  
  
• They must leave early. (Not: They must to leave)
  
  

C. Split Infinitives

A split infinitive occurs when an adverb is placed directly between the word "to" and the base verb:

• To boldly go where no one has gone before.
  
  
• He promised to carefully review the document.
  
  

D. Negative Infinitives

To make an infinitive negative, simply place the word "not" directly before "to":

• She decided not to go to the party.
  
  
• Please try not to make noise.
  
  

Infinitive Verb: An infinitive verb must always come after the first verb. In other words, an infinitive will always be the second verb in a sentence.

Some sentences may have two infinitive verbs as shown in the following example: 1."Uncle Jim lives in my house to help, to guide my school-going kid".

Two infinitive verbs may be joined by the conjunction, 'and' like this: "The king led his troops to conquer and to annex the nearby country".

Part 5: Multiple Infinitives in a Single Sentence

A sentence can include more than one infinitive verb connected sequentially or with conjunctions:

1. Sequential Infinitives: "Uncle Jim lives in my house to help, to guide my school-going kid."
   
   
2. Joined by Conjunctions: "The king led his troops to conquer and to annex the nearby country.
