Comparatives and Superlatives in the TOEIC®: Rules, Pitfalls, and Strategy to Eliminate Errors

Comparatives and superlatives allow you to compare elements (bigger, less expensive) or express an absolute degree (the fastest, the least expensive).

In the TOEIC®, these frequently appear in Parts 5 and 6, and you must know whether to choose between "-er/more" and "-est/most" based on the adjective length.

The main pitfall? Confusing the forms (saying "more fast" instead of "faster") or forgetting "than" after a comparative. Today, we'll go over all of that together so you won't make mistakes anymore ;)

The Basics: How to Form Comparatives and Superlatives

The rule depends on the number of syllables in the adjective.

Short Adjectives (1 Syllable): -er / -est

You add "-er" for the comparative and "-est" for the superlative.

• "This contract is shorter than the previous one."
• "Our newest product is the cheapest option on the market."

2-Syllable Adjectives: It Depends

For adjectives ending in -y, -ow, -le, -er: use "-er/-est" (change -y to -i).

• "The second proposal is easier to implement."

For other 2-syllable adjectives: use "more/most".

• "This process is more careful than the old one."

Long Adjectives (3+ Syllables): more / most

• "The new software is more efficient than the previous version."
• "She submitted the most detailed report in the team."

Irregular Adjectives to Memorize

With the candidates we coach for TOEIC preparation, we see the same thing time and again: the majority of mistakes on this topic in Part 5 involve "good/better/best" and "bad/worse/worst".

Summary Table of Forms

TOEIC® Traps in Comparisons

The rules are set.
But in the TOEIC®, knowing the rule isn't always enough. It's often the details that cause you to lose points, especially when you're moving fast.

This is exactly where the test creators trap many candidates. Let's look at the most common errors and how to avoid them.

Trap 1: Double Marking, Choosing Between more and -er

In the TOEIC®, you can never use:

• more with an adjective already in the -er comparative form
• nor most with -est.

--> Therefore, if the adjective takes -er / -est, we never add more / most.

"more faster" / "most easiest" → Incorrect form
"faster" / "easiest" → Correct form

Here is a summary table you can memorize as is:

Trap 2: Forgetting "than" after a Comparative

Comparatives of superiority (-er / more) require "than" to introduce the second element.

• "Sales in Q2 were higher than in Q1."

Trap 3: Confusing "less" and "fewer"

"Less" is used with uncountable nouns, "fewer" with countable nouns.

As a reminder, a noun is countable if it can be counted individually (one, two, three…). If it cannot, then it is uncountable because it denotes a total quantity that is not counted item by item.

• "We received fewer applications this year."
• "There is less time available for the meeting."

Trap 4: Forgetting "the" before the Superlative

The superlative always takes "the" (unless preceded by a possessive).

• "This is the most important document." --> without possessive
• "Our best employees receive bonuses." --> with possessive

Comparisons of Equality and Inferiority

As... as (Equality)

• "The new office is as large as the previous one."

Not as... as (Inferiority)

• "This quarter was not as profitable as the last one."

Less... than (Inferiority)

• "The second option is less expensive than the first."

Candidates who progress quickly have a simple reflex: they spot the keywords "than" and "as" in the sentences to identify that it is a comparison, then they check the adjective form.

Advanced Structures that Appear in Part 5

The... the... (The more... the more...)

• "The more you practice, the better you get."

This structure often appears in business contexts: "The sooner we respond, the more satisfied our clients will be."

Much / far / a lot + Comparative (Intensification)

• "This solution is much more efficient than the old one."

By far + Superlative (By far)

• "She is by far the most qualified candidate."

Checklist

When you see a blank to fill with an adjective, ask yourself these questions in order:

Frequent Errors Seen Among Our Candidates

It is often with incorrectly used "as... as" structures that candidates lose the most points, much more than on the "-er/-est" forms themselves. Remember to check the entire structure, not just the isolated adjective.

Ready to Practice?

You have now mastered the essential rules for comparatives and superlatives.

The secret to fast progress? Identify the keywords ("than", "the", "as"), check the adjective's syllable count, and spot the irregulars.
