The idea in one minute

A connector blank is a logic question. The connector must name the exact link between the clause before it and the clause after it. Decide the direction first: opposite, cause, result, addition or time. Then choose the word.

01

What a connector blank tests

A connector joins two clauses. Your job is to find the direction between them. The connector is logic written as one word.

Rule: Split the sentence at the blank. Ask how clause B behaves toward clause A.

02

Step 1: find the two clauses

Give each side a sign. Use + for a good point and - for a bad point.

  • The walk costs nothing (+), ___ very few continue it (-). The signs are opposite, so this is contrast.
  • It rained heavily, ___ the match was cancelled. B is the outcome of A, so this is result.
  • Prices rose, ___ wages stayed flat. B adds a parallel point, so this is addition.
  • She finished her homework, ___ the lights went out. One event follows the other, so this is time.
03

Step 2: pick the family, then the word

RelationConnectorsMini-test
Contrastbut, yet, however, although, whereas, still, whileThe clauses pull in opposite directions
Causebecause, since, as, forB explains why A is true
Resultso, therefore, hence, thus, consequentlyB is the outcome of A
Additionmoreover, besides, also, and, furthermoreB adds a parallel point
Conditionif, unless, providedOne clause depends on the other
Timewhen, while, before, after, untilOne clause fixes when the other happens

Tip: The most common exam item is praise followed by a limit. The walk costs nothing and needs no equipment, ___ very few people continue it. The blank needs yet or but.

04

Step 3: use the punctuation clue

  • After a full stop or a semicolon, a linking word plus a comma is used: however, moreover, therefore, otherwise. Example: Business has not suffered; moreover, some customers order a second cup.
  • A single comma joining two clauses takes but, yet, so, for, and.
  • A blank at the start of a second sentence often looks back at the whole first sentence.
05

Pairs and confusions

Some connectors come in pairs: not only ... but also, either ... or, neither ... nor, both ... and, no sooner ... than, hardly ... when, lest ... should. If you see one half outside the blank, only its partner fits.

  • but or so: The shop is small, ___ it is always full. Use but. The road was cleared, ___ traffic flowed again. Use so.
  • because or although: ___ it rained, the match went on. Use Although, because the result is surprising. ___ it rained, the match was cancelled. Use Because.
  • while has two meanings: time (read while the tea cools) and contrast (cities grew rich, while villages lagged).
  • until shows an action running up to a point: He waited until morning.

Watch: However and therefore need commas around them. Yet, but and so join clauses directly after a comma.

Question types you will see

Each type: how to recognise it, the method step by step, and one question to try.

Type 1very common2 practice Q

Contrast connector (but, yet, although, whereas)

How to spot it:

One clause is good and the other is bad, or one is expected and the other is surprising.

Method
  1. Give each clause a + or - sign.

  2. If the signs are opposite, choose a contrast word.

  3. Check that the word fits the punctuation.

Why it works:

Opposite signs mean the second clause pulls against the first.

Try this

The walk costs nothing, ___ very few people continue it. Options: yet / so / because / and.

Show solution
  1. The first clause is good (+).

  2. The second is a limit (-).

  3. Only yet shows contrast.

Answer

yet

Type 2very common3 practice Q

Reason connector (because, since, as)

How to spot it:

The second clause explains why the first clause is true.

Method
  1. Ask: does one clause explain the other?

  2. The explaining clause follows because.

  3. Read both clauses with your choice.

Why it works:

A reason connector links an event to its cause.

Try this

The match was cancelled ___ it rained heavily. Options: because / although / but / so.

Show solution
  1. Rain is the reason for the cancellation.

  2. Because introduces the reason.

Answer

because

Type 3common3 practice Q

Addition connector (moreover, furthermore, besides)

How to spot it:

The second sentence adds one more point in the same direction.

Method
  1. Check that both clauses have the same sign.

  2. Pick an addition word.

  3. Use the punctuation: semicolon, word, comma.

Why it works:

The writer is building up one point, not turning against it.

Try this

Business has not suffered; ___, some customers now order a second cup. Options: moreover / otherwise / unless / until.

Show solution
  1. Both parts are good news.

  2. The second adds to the first.

  3. Moreover adds a point.

Answer

moreover

Type 4common3 practice Q

Time connector (while, until, before, after, when)

How to spot it:

One clause tells when or for how long the other happens.

Method
  1. Find the two events.

  2. Decide their order: before, after, together or up to a point.

  3. Choose the time word for that order.

Why it works:

Time words place two events on one timeline.

Try this

Please wait here ___ the doctor arrives. Options: until / unless / although / because.

Show solution
  1. Waiting continues up to the doctor's arrival.

  2. Until shows this.

Answer

until

Type 5common

Result connector (so, therefore, hence)

How to spot it:

The second clause is the outcome of the first.

Method
  1. Ask: did the first clause cause the second?

  2. Choose so or therefore.

  3. Check the punctuation.

Why it works:

A result connector shows what followed from a cause.

Try this

The road was cleared, ___ traffic flowed again. Options: so / but / because / although.

Show solution
  1. Clearing the road caused the flow.

  2. The second clause is the result.

Answer

so

Type 6occasional

Pair connector (not only ... but also)

How to spot it:

One half of a pair, such as not only, either or neither, is outside the blank.

Method
  1. Spot the half that is already there.

  2. Recall its partner.

  3. Choose it.

Why it works:

Correlative pairs always come as a set.

Try this

He is not only honest ___ also hardworking. Options: but / and / or / nor.

Show solution
  1. Not only is already in the sentence.

  2. Its partner is but also.

Answer

but

Type 7common

Linking word after a full stop

How to spot it:

The blank starts a new sentence and a comma follows it.

Method
  1. Read the sentence before the blank.

  2. Decide how the new sentence relates to it.

  3. Choose the linking adverb.

Why it works:

Sentence-starting connectors look back at the whole earlier sentence.

Try this

The plan looked perfect. ___, it failed on the first day. Options: However / Because / So / Unless.

Show solution
  1. The plan looked good.

  2. It failed, which is the opposite.

  3. However shows contrast.

Answer

However

07

Shortcuts that save time

⚡ Opposite-direction test

Give each clause a + or - sign. Same signs point to addition or result. Opposite signs point to contrast.

Example

The walk costs nothing and demands no equipment (+), ___ very few people continue it (-).

Show solution
  1. The signs are + then -.

  2. Opposite signs need a contrast word.

Answer

yet / but

⚡ Partner hunt

Scan the sentence for the other half of a pair. If you see not only, the blank must be but also. No further thinking is needed.

⚡ Comma tell

A pattern like clause, ___ clause with a one-word slot wants yet, but, so, for or and. Options like however and therefore fit the pattern clause. ___, clause instead.

08

Mistakes to avoid

Where most students lose marks on this subtopic.

Mistake 01

Mixing up result (so) and cause (because).

Ask which clause explains which. The reason follows because. The outcome follows so.

Mistake 02

Using although where a plain but is needed.

Although starts a subordinate clause. It cannot join two full clauses as but does.

Mistake 03

Choosing a connector that fits the sentence but reverses the paragraph's argument.

Check the choice against the flow of the whole passage.

Mistake 04

Marking and as always safe.

In a contrast context, and destroys the writer's point.

09

Quick revision

Read this the night before the exam.

  • A connector shows the direction between two clauses. Find both clauses first.

  • Contrast: but, yet, however, although, whereas.

  • Result: so, therefore, hence. Reason: because, since, as.

  • Addition: moreover, besides. Time: when, while, until, before.

  • Full stop or semicolon + comma: however, moreover, therefore, otherwise.

  • because = normal result. although = surprising result.

  • Read the full joined sentence aloud to test your choice.
