TOEIC Link Part 5: Comparatives, Superlatives, and the Words That Force Them

Comparison questions in TOEIC Link Part 5 look like they test vocabulary, but they almost never do. They test whether you can read a small set of trigger words and let those words pick the form for you. Once you see than, the, or as … as as switches rather than as meaning, the blank fills itself. This guide teaches you to spot the trigger, read the form it demands, and answer without weighing what the sentence actually says.

The three forms and what each one is for

Every adjective and adverb has three degrees, and Part 5 expects you to keep them straight:

• Positive — the base form: fast, efficient, carefully
• Comparative — comparing two things: faster, more efficient, more carefully
• Superlative — singling out one from three or more: fastest, most efficient, most carefully

The rule for which spelling to use is mechanical. One- and two-syllable words usually add -er / -est (quick → quicker → quickest). Longer words take more / most (reliable → more reliable → most reliable). Adverbs ending in -ly almost always take more / most (quickly → more quickly). You do not have to decide this from meaning — the word's shape decides it.

The trigger words that force a comparative

When you see any of these, the answer is a comparative form, every time:

• than — the single most reliable signal. If than appears, the blank in front of it is a comparative.

Sales this quarter were ( ) than last quarter. → higher (not high, not highest)

• comparative + and + comparative — the "increasingly" pattern.

The schedule is becoming ( ) and tighter. → tighter

• the + comparative … the + comparative — paired change.

The ( ) we order, the lower the unit cost. → more (as in the more we order)

The moment you see than, stop reading for meaning. Find the blank in front of it and supply the comparative.

The trigger words that force a superlative

Superlatives single one item out of a group, and they come with their own signals:

• the directly before the blank, plus a group of three or more

Of all our suppliers, they offer the ( ) prices. → lowest

• in / of + a group following the adjective

This is the ( ) branch in the region. → largest

• ordinal-style framing — one of the …, among the …

It is one of the ( ) reliable models we sell. → most

The tell for a superlative is the hugging the adjective together with a defined group (in the region, of all our suppliers, on the team). Comparatives compare two things and use than; superlatives rank within a set and use the … in/of.

The as … as trap

The correlative as … as looks like a comparison, but it demands the positive form, not the comparative:

The new model is as ( ) as the previous one. → efficient (not more efficient)

Many test-takers see "comparison" and reach for the -er form. The frame as … as overrides that instinct: whatever sits between the two as words stays in its base form. Train your eye to read as … as as a positive-form bracket.

A common irregular set worth memorizing

A handful of high-frequency words do not follow the spelling rule, and Part 5 uses them often:

• good → better → best
• bad → worse → worst
• far → farther/further → farthest/furthest
• little → less → least
• many/much → more → most

If you see than after good, the answer is better, never gooder or more good. These are pure recognition — drill them until they are automatic.

The two-step method on sight

For any comparison question, run two checks before you look at the options:

1. Scan for the trigger. Is there a than (→ comparative), a the … in/of frame (→ superlative), or an as … as bracket (→ positive)?
2. Apply the spelling rule. Short word → -er/-est; long word or -ly adverb → more/most; irregular → recall the set.

That is the entire decision. You never need to evaluate whether one thing is genuinely faster than another — the grammar of the sentence has already told you which form belongs in the blank.

This is the same evidence-before-meaning habit that wins Part 5 across every category. If the question of whether you are being tested on form or on meaning still feels blurry, review word choice versus word form — comparison questions are squarely form questions, and treating them that way is what makes them fast.

To keep building reflexes from the predictable, mechanical corners of Part 5, pair this with the list-matching skill, since both reward pattern recognition over comprehension. If you have not drilled it yet, see parallel structure. The more of these you convert into instant recognition, the more of Part 5 becomes a matter of spotting a switch and flipping it — and that is where your time savings come from.
