TOEIC Link comparatives and superlatives — adjective and adverb rules, intensifiers, and the six common Part 5 / 6 traps

Basic rules for comparatives and superlatives

The comparative and superlative form of an adjective or adverb depends on syllable count. Single-syllable words (fast, tall, big) take -er / -est. Words of three or more syllables (important, beautiful) use more / most. Two-syllable words split: those ending in -y (happy, easy, busy) take -ier / -iest, while others (modern, useful, careful) take more / most by default. Examples: tall → taller → tallest, important → more important → most important, busy → busier → busiest.

Memorizing irregular forms removes hesitation in Part 5: good → better → best, bad → worse → worst, many / much → more → most, little → less → least, far → farther / further → farthest / furthest. The "farther vs further" distinction comes up too — farther is the standard for physical distance ("Tokyo is farther from Osaka than Kyoto"), while further covers abstract progression ("We need further discussion"), with some American/British variation.

The basic comparative structure "A is + comparative + than + B" is straightforward, but when the subject after than is a pronoun, formal usage takes the nominative ("taller than I am") while colloquial usage takes the objective ("taller than me"). TOEIC Link's business-document context favors formal, so the nominative + be-verb pattern is safer.

Superlatives default to "the + superlative + noun" (the tallest building). The "the" is omitted when a possessive or determiner is already present (Tokyo's tallest building, my best friend). The "one of the + superlative + plural noun" pattern is also frequent (one of the most popular products) — note that the noun must be plural here.

• 1 syllable: -er / -est (tall → taller → tallest)
• 3+ syllables: more / most (important → more important → most important)
• Irregular: good/bad/many/little/far
• Comparative: A is + comparative + than + B
• Superlative: the + superlative + noun / one of the + superlative + plural

Intensifiers and quantitative modifiers

Adverbs that strengthen a comparative are limited: much / far / a lot / considerably / significantly / substantially / even. Examples: "This product is much more expensive than the old one" / "Sales grew significantly faster than projected." Note that "very" cannot modify a comparative ("very better" is wrong) — very can only intensify the positive form. This is a frequent Part 5 trap.

Adverbs that weaken a comparative include a little / slightly / somewhat / a bit. Example: "The new model is slightly heavier than the previous one." Note that "a little" and "little" differ — "a little" means "slightly (positive nuance)" while "little" means "almost no (negative nuance)." Saying "little better" implies "almost not better."

Superlative intensifiers include by far / easily / among the / arguably. Examples: "This is by far the best option" / "It is easily the most efficient method" / "She is among the most experienced engineers" / "It is arguably the most important factor." When Part 5 asks for an intensifier of a superlative, recognize these candidates.

The correlative comparative "the + comparative, the + comparative" also appears on TOEIC Link. Examples: "The more you practice, the better you get" / "The faster the response, the higher the customer satisfaction." Recognizing that both clauses must take "the + comparative" form keeps you from missing this Part 5 pattern.

• Comparative intensifiers: much / far / a lot / significantly / even
• "very" cannot modify a comparative ("very better" is wrong)
• Comparative weakeners: a little / slightly / somewhat
• Superlative intensifiers: by far / easily / among the / arguably
• Correlative: the + comparative, the + comparative

Six common Part 5 / 6 traps

*Trap 1: Omitted comparison object and parallel structure*. "Sales in Q4 were higher than ___" should be filled with "those in Q3" or "in Q3," not just "Q3." "Sales in Q4 were higher than Q3" compares "sales vs Q3 (the time period)," which is logically inconsistent. Parallel structure requires the than-clause to take the same form as the subject side.

*Trap 2: Mixing 'as ... as' and comparative*. The positive comparison "as + base form + as" cannot mix with the comparative "comparative + than." "as expensive than" is wrong; the correct forms are either "as expensive as" or "more expensive than." The negative is "not as ... as" (= less ... than): "This year's revenue is not as high as last year's" = "lower than last year's."

*Trap 3: Determiner conflict with the superlative*. If a possessive or determiner is already there, "the" is unnecessary ("our most reliable supplier" is correct; "our the most reliable supplier" is wrong). Conversely, when a superlative + noun lacks a determiner, "the" is required ("most reliable supplier" is wrong; "the most reliable supplier" is correct). Part 5 questions on missing or extra "the" can be answered fast once this rule is internalized.

*Trap 4: Singular/plural mismatch with comparatives*. The "one of the + superlative + plural" rule is often missed. "This is one of the most popular product" is wrong; it must be "products." The same applies to "any of the + noun" and "all of the + noun" — plural is the default. When choices include both singular and plural, pick the plural.

*Trap 5: Latin-origin comparatives take "to," not "than"*. Verbs and adjectives like "prefer A to B," "preferable to," "superior to," "inferior to," "senior to," "junior to" all take "to" instead of "than" because they carry comparative meaning despite lacking the -er suffix. When these words appear in Part 5, fill the prepositional slot with "to."

*Trap 6: Double comparatives*. Do not add "more" to a word that already has -er ("more taller" is wrong, just "taller"). Do not add "most" to a word that already has -est ("most tallest" is wrong, just "tallest"). Conversely, do add "more / most" to words that do not undergo regular suffix change ("more important"). When choices include double comparatives, eliminate them immediately.

Frequent expressions in Listening and Reading

Comparatives and superlatives are frequent in Listening Part 4 announcements / talks for performance reports: "Our Q4 revenue was the highest in the company's history" / "Customer complaints decreased by 30% — the largest decline in three years" / "This year's growth rate is significantly higher than last year's." Catching the superlative in the talk often answers the question "What is the speaker reporting?" immediately.

In Reading Part 7 newsletters and press releases, fixed superlative phrases like "the leading provider," "the most trusted brand," "the fastest-growing segment," and "among the top 10" recur. Familiarity with these idiomatic phrases speeds up reading.

Comparison framing phrases — "compared to," "in comparison with," "relative to," "as opposed to" — appear in Part 6 / Part 7 chart-description text. "Sales grew by 15% compared to the previous year" / "Marketing spend remained stable relative to revenue." Picking up these comparison frames first in number-heavy passages anchors the context fast.

EnglishBlitz Reading drills include many business documents (annual reports, quarterly reviews, market research) that use comparative and superlative patterns idiomatically, building pattern-recognition rather than rule-recall. Test-takers who hit 90%+ accuracy on Part 5 comparison questions consistently report relying on phrase recognition rather than grammar rules.
