TOEIC Link Reading — Part Five Connector-Word Selection: Telling Subordinating Conjunctions, Prepositions, and Conjunctive Adverbs Apart Under Time Pressure

Connector-word questions are the item type that punishes candidates who read for meaning instead of structure. A connector question offers four choices that translate almost identically into the test-taker's first language — because, because of, therefore, due to — and asks which one fits the blank. Because the four choices carry nearly the same meaning, the candidate who chooses by meaning has no way to eliminate anything and falls back to a guess. The candidate who chooses by structure eliminates three choices in a single pass, because each connector type is licensed by a different grammatical environment. The correct answer is never the one that means the right thing; it is the one whose category matches what follows the blank.

This is the natural companion to the two-way distinction covered in conjunction-versus-preposition selection, and it shares its underlying logic with word-form and derivational-suffix selection: read the slot before you read the choices. The three-way version simply adds a third category — the conjunctive adverb — that most candidates never learn to separate from the other two.

The three connector categories and what each one is allowed to attach to

The entire item type reduces to one question: what comes after the blank? Answer that, and the connector category is forced.

Category one — the subordinating conjunction

A subordinating conjunction (because, although, while, since, if, when, unless, so that) introduces a full clause: a subject plus a finite verb. If the words after the blank form a complete idea that could almost stand alone — the shipment was delayed, the client had already approved the terms — the blank needs a conjunction.

• Test: blank + subject + verb → subordinating conjunction.
• Example: "___ the invoice was submitted late, payment will still be processed this week." The clause _the invoice was submitted late demands Although or Because, never Despite.

Category two — the preposition

A preposition (because of, due to, despite, during, in spite of, owing to) attaches to a noun phrase only — a noun, a pronoun, or a gerund — never to a subject-plus-verb clause. If the words after the blank are a noun phrase with no finite verb, the blank needs a preposition.

• Test: blank + noun phrase (no finite verb) → preposition.
• Example: "___ the late submission, payment will still be processed." _The late submission is a noun phrase, so the answer is Despite or Because of, never Although.

Category three — the conjunctive adverb

A conjunctive adverb (however, therefore, nevertheless, moreover, consequently, otherwise) does not join two clauses grammatically at all. It sits inside or beside an independent sentence — usually after a semicolon or a period, often set off by a comma — and signals the logical relationship to the previous sentence. If the blank sits at the start of a new independent sentence, or after a semicolon, and is followed by a comma and a complete clause, the blank needs a conjunctive adverb.

• Test: semicolon or full stop before the blank, comma after it, independent clause following → conjunctive adverb.
• Example: "The vendor missed the deadline; ___, the contract allows a five-day grace period." The semicolon and the standalone clause force _however or therefore, never although or despite.

The seven distractor patterns item writers rely on

1. Same meaning, wrong category. because / because of / therefore all express cause; only the structure decides. This is the core trap.
2. Concession swap. although (conjunction) versus despite (preposition) versus however (adverb) — all mean "contrast," all three appear as choices.
3. The bare noun bait. A gerund after the blank (being late) looks verb-like and tempts a conjunction; it is a noun phrase and needs a preposition.
4. The semicolon tell. A semicolon earlier in the sentence signals a conjunctive adverb, but candidates skim past punctuation.
5. Front-loaded clause. A comma mid-sentence hides whether the following words are a clause or a phrase; the finite verb is the only reliable signal.
6. Reversed logic. The sentence's logic (contrast versus cause) narrows the choice within the correct category, so category-matching alone is not always enough — read for logic only after category-matching.
7. The adverb-as-conjunction error. Candidates use however to join two clauses with a comma (a comma splice); the test never rewards that, so a comma-only join rules out the conjunctive adverb.

The four-week protocol

Week one — category drills only. Take fifty Part Five connector items and, for each, write only the letter of the category (C for conjunction, P for preposition, A for adverb) after reading only the words that follow the blank. Do not choose an answer yet. Build the reflex of classifying the environment before the meaning.

Week two — category then logic. Now add the second step: within the correct category, choose contrast versus cause versus addition by the sentence's logic. Time yourself to under twenty-five seconds per item.

Week three — punctuation-first scan. Train yourself to glance at punctuation before words: a semicolon or period near the blank flags the conjunctive adverb instantly and eliminates two categories before you read anything.

Week four — mixed timed sets. Run forty-item mixed sets under strict Part Five pacing, targeting under twenty seconds per connector item so you bank time for the harder vocabulary-in-context questions later in the set.

The one-sentence rule to carry into the exam

Read what follows the blank first: a subject-plus-verb clause takes a conjunction, a bare noun phrase takes a preposition, and a new independent sentence after a semicolon or period takes a conjunctive adverb. Meaning only breaks the tie within the winning category — it never picks the category. Master that order of operations and connector questions stop being guesses and become the fastest reliable points in the Part Five set.
