How This Grammar Works

At the C1 level, your goal is to move beyond simply conveying information to shaping understanding and building sophisticated arguments. The grammar points in this chapter are designed to help you do just that, acting as powerful linguistic bridges between your ideas. They allow you to add layers of detail, ensure comprehension, and manage the flow of information seamlessly.
Let's start with 'in other words'. This phrase is your go-to for simplifying or rephrasing a complex statement, ensuring your audience grasps the core message. For example: "The company's strategic realignment involved a pivot towards agile methodologies; in other words, they shifted to a more flexible and responsive operational model." It’s about clarity and conciseness.
Next, when you need to substantiate your claims or add depth to your explanations, 'for instance' is invaluable. It introduces specific examples that bring abstract ideas to life.
Many developing nations face significant infrastructure challenges; for instance, a lack of reliable transportation networks often hinders economic growth.
This provides concrete evidence.
To manage parallel events or shift focus within a narrative without losing coherence, we use 'meanwhile'. It signals that something else is happening concurrently.
The lead researcher meticulously analyzed the experimental data; meanwhile, her team prepared the preliminary findings for presentation.
It adds a dynamic dimension to your storytelling.
When discussing cause and effect, especially in formal or professional contexts, 'consequently' is the precise link you need. It highlights a direct, logical result.
The new legislation significantly reduced import tariffs; consequently, consumer prices for electronic goods are expected to decrease.
It’s a clear marker of logical progression.
Finally, for assertive emphasis, to provide surprising information, or to politely correct a misconception, 'as a matter of fact' is perfect.
I thought the project deadline was next Friday. As a matter of fact, it was moved up to this Wednesday, so we need to accelerate our efforts.
This phrase adds weight and authority to your statements.
These connectors, used together, allow you to construct a coherent, persuasive, and nuanced discourse.

Common Mistakes

  1. 1✗ Overusing 'Consequently' in informal settings: While a powerful formal connector, using 'consequently' in casual speech can sound stiff or overly academic.
✓ Correct:
I missed the bus, so I was late.
(Informal)
✓ Correct:
The budget cuts led to a reduction in staff; consequently, productivity declined.
(Formal)
*Explanation:* Reserve 'consequently' for more formal discussions or written work. For everyday situations, simpler connectors like 'so' or 'because of that' are more natural.
  1. 1✗ Misplacing 'Meanwhile': Putting 'meanwhile' in the wrong part of the sentence can confuse the timing of events.
✓ Correct:
The students began their essays. Meanwhile, the professor graded their previous assignments.
✗ Wrong:
The students, meanwhile, began their essays the professor graded their previous assignments.
*Explanation:* 'Meanwhile' typically starts a new independent clause or is placed after the subject of a new clause to indicate simultaneous action, often shifting focus.
  1. 1✗ Using 'As a matter of fact' aggressively: While it asserts information, using it with the wrong intonation can come across as confrontational.
✓ Correct: (Politely)
Oh, I thought he lived in Paris. As a matter of fact, he moved to Rome last year.
✗ Wrong: (Aggressively) "You're wrong. As a matter of fact, it's this way!"
*Explanation:* The tone is crucial. 'As a matter of fact' is about providing precise information, often corrective, but it should be delivered diplomatically in most social contexts.

Quick FAQ

Q

When should I use 'in other words' instead of 'that is to say'?

While similar, 'in other words' is generally used to simplify or restate something in a clearer, often less formal way. 'That is to say' can also simplify, but often introduces a more precise or explanatory reformulation, sometimes with a slightly more formal or academic tone.

Q

Is 'consequently' always interchangeable with 'therefore' or 'as a result'?

They are often interchangeable when expressing a result. However, 'consequently' tends to emphasize the direct, logical outcome of a preceding action or event more strongly, especially in formal writing. 'Therefore' often indicates a logical deduction or conclusion, and 'as a result' is a very general causal link.

Q

Can I start a sentence with 'as a matter of fact'?

Absolutely! It's very common to use 'as a matter of fact' at the beginning of a sentence to introduce a piece of information that is surprising, corrects a previous statement, or adds emphasis.

Q

How does 'meanwhile' differ from 'at the same time'?

'At the same time' simply indicates simultaneity. 'Meanwhile' also indicates simultaneity but often implies a shift of focus or a separate, ongoing action that provides context or contrast to the main narrative. It's more narrative-driven.

Cultural Context

Native English speakers use these connectors constantly, though their formality varies. 'In other words' is very versatile, appearing in both casual and formal contexts. 'For instance' is also widely used.
'Consequently' and 'as a matter of fact' lean towards more formal or assertive communication; while understood casually, they're more prevalent in professional discourse, debates, or written analysis. 'Meanwhile' is a common narrative device, especially in storytelling or describing unfolding events. There are no significant regional differences in their core meanings, but individual preferences for formality might vary slightly across different English-speaking cultures.

💡

表現を使い分けてみましょう

いつも同じフレーズばかり使わないで！「for instance」も素晴らしいですが、「for example」や「such as」なども使ってみたり、文章の構成自体を変えてみたりするのも良い練習になります。「Variety makes your language more engaging.」

継続している行動に注目しよう

「Meanwhile」は、両方の出来事が継続的であるか、ある程度の期間にわたって起こっている場合に最も効果的です。テレビの分割画面のように、二つのことを同時に見せていると考えてみましょう。「Meanwhile works best when both events are continuous or spanning a period of time. Think of it like a split screen on your TV, showing two things at once."

The Strategic Meeting

Review Summary

  • [Statement], in other words, [rephrased statement].
  • [Subject] + [Verb] + [that/wh-clause].

よくある間違い

When the reporting verb is in the past, the verb in the noun clause usually shifts to the past.

Wrong: He said that he is coming.
正解: He said that he was coming.

Consequently is a conjunctive adverb, not a conjunction; it needs a semicolon or a full stop.

Wrong: Consequently, he was tired, he slept.
正解: He was tired; consequently, he slept.

Always set off introductory phrases with a comma for better readability.

Wrong: As a matter of fact it is true.
正解: As a matter of fact, it is true.
