Overview

Ready to elevate your English from proficient to truly persuasive? As a C1 learner, you’ve mastered complex grammar, but now it’s time to fine-tune your professional communication and logic. This chapter isn’t just about knowing more words; it’s about wielding them with precision to make your arguments undeniable and your insights deeply impactful.
We’ll explore how to stack your points seamlessly with markers like moreover and furthermore, and how to articulate causes with elegant phrases such as owing to and in view of.
You’ll discover how to signpost conclusions powerfully using hence, thus, and accordingly, ensuring your formal results are crystal clear. Beyond direct statements, we’ll also delve into the subtle art of modal hedging, employing words like might and could to present claims with academic rigor and appropriate caution. By mastering these nuanced tools, you'll not only improve your C1 English grammar but also gain the confidence to express sophisticated ideas fluently and spontaneously in any professional setting.
Get ready to write and speak with authority and finesse!

How This Grammar Works

Imagine constructing a compelling case, point by meticulous point. To build an argument robustly, you start by adding supporting evidence. Instead of simply saying also, at a C1 level, you'll use moreover and furthermore.
For example,
The market share has increased; moreover, customer satisfaction surveys show higher ratings.
These linkers add weight and formality. When explaining *why* something happened, move beyond because. For formal reasons, use phrases like owing to and in view of, followed by a noun.
The project was delayed owing to unforeseen technical difficulties,
or
In view of the budget constraints, we decided to postpone the launch.
Once you've presented your reasons, you need to clearly state the consequences. For formal results, choose hence, thus, or accordingly.
Hence, a new strategy is required.
Thus, we adjusted our projections.
Accordingly, new resources were allocated.
To narrate a series of events professionally, especially in reports, subsequently and thereafter are invaluable.
The data was collected; subsequently, it was analyzed.
Finally, when you've made your points, you need to tie them up neatly. In sum and to recapitulate are your go-to phrases for signaling a concise conclusion.
To recapitulate, the key findings support a phased approach.
Beyond direct statements, true mastery involves nuance.
Modal hedging with words like might or could is crucial for academic and professional integrity. Instead of
This *is* the solution,
consider
This *might be* a viable solution,
or
The evidence *could suggest* a correlation.
This demonstrates careful consideration and intellectual honesty. These tools collectively empower you to construct arguments with impressive precision.

Common Mistakes

Even advanced learners can stumble with these precise terms. Here are some common pitfalls:
  1. 1Misusing 'Owing to' with clauses:
✗ The meeting was canceled owing to that the CEO was ill.
✓ The meeting was canceled owing to the CEO's illness.
*Explanation:* Owing to requires a noun phrase or gerund, not a full clause. For clauses, use 'because' or 'since'.
  1. 1Overusing 'Hence' at the beginning of a sentence:
✗ Hence, we will proceed. (While not strictly wrong, it can sound overly abrupt or repetitive if always at the start)
✓ The analysis is complete; hence, we can now make an informed decision.
✓ We have concluded the analysis; we will accordingly make an informed decision.
*Explanation:* Hence, thus, and accordingly often work best as transitions within or between sentences, or to follow a clear premise. Don't rely on them as simple sentence starters without strong preceding context.
  1. 1Applying modal hedging to established facts:
✗ It might be possible that water boils at 100°C.
✓ Water boils at 100°C. (Or: The experiment might indicate a different boiling point under specific conditions.)
*Explanation:* Modal hedging is for claims, interpretations, or predictions, not universally accepted facts. Use it to introduce an element of uncertainty or possibility where it truly exists.

Real Conversations

Let's see these in action in everyday professional scenarios.

Scenario 1: Project Update

A

A

How are we looking for the Q3 report deadline?
B

B

We've encountered some unexpected data discrepancies; owing to a system error, a portion of the sales figures was corrupted. Subsequently, the team has been working overtime to manually verify the records.
A

A

So, what’s the revised timeline?
B

B

In view of these challenges, we might need a two-day extension.

Scenario 2: Team Meeting Discussion

I agree, the data thus far clearly supports that move.

Quick FAQ

Q: When should I use moreover versus furthermore?

Both are interchangeable for adding points formally. Furthermore can sometimes feel slightly stronger or imply

in addition to what has been said, here’s an even more important point,
but for most contexts, they function identically in professional communication and logic.

Q: Is thusly a correct word? Should I use it instead of thus?

While thusly exists, it is widely considered archaic or overly formal and often sounds affected. Stick with thus for clear, concise, and modern C1 English grammar.

Q: Does modal hedging make me sound indecisive in professional settings?

Quite the opposite! Using words like might or could (modal hedging) demonstrates careful consideration, intellectual humility, and an understanding that professional claims often involve a degree of uncertainty or interpretation. It signals a sophisticated approach to professional communication and logic.

Cultural Context

Native English speakers predominantly reserve these specific formal linkers for written professional contexts, academic papers, and very formal presentations. You'll rarely hear hence or in view of in casual conversation. The judicious use of modal hedging, however, is common across many levels of formal and semi-formal speech, indicating thoughtfulness rather than uncertainty.
Understanding this distinction helps you sound authentic and appropriately formal without sounding stiff or unnatural.

ヒントとコツ (4)

💡

文章の「フォーマル度」を上げる秘訣

プレゼンテーションや公式文書で、あなたの文章を一瞬で格上げしたい時、これらの単語はとても役立ちます。「and」や「also」よりも洗練された、アイデアのつながりを示すことができますよ。"They signal a more sophisticated connection between ideas than simple 'and' or 'also'."
frontend.learn_grammar.from_rule: 情報を正式に追加する方法:Moreover & Furthermore
💡

いつも名詞のように

「owing to」も「in view of」も前置詞なので、必ず名詞、名詞句、動名詞、または代名詞が続きます。主語と動詞のある完全な節は絶対に来ません。「The event was postponed owing to low registration.」
frontend.learn_grammar.from_rule: 正式な理由: owing to と in view of
💡

句読点に注意!

これらの言葉が新しい節を導入する際は、必ずセミコロン(;)かピリオド(.)を前に置き、その後にカンマ(,)を続ける必要があります。これにより、明確さと適切な文法の流れが保たれます。「The report was late; hence, the meeting was rescheduled.」
frontend.learn_grammar.from_rule: 正式な結果:Hence, Thus, Accordingly
💡

文脈が一番大事!

書いている内容の文脈を常に考えてくださいね。フォーマルな文書では、「subsequently」と「thereafter」は素晴らしい選択肢です。でも、カジュアルなチャットでは、ロボットみたいに聞こえないように「then」や「after that」を使いましょう。「For casual chats, stick to 'then' or 'after that' to avoid sounding like a robot.」
frontend.learn_grammar.from_rule: 正式な順序:SubsequentlyとThereafter

  • [Sentence]; hence/thus/accordingly, [sentence].
  • [Event 1]. Subsequently, [Event 2].

よくある間違い

Owing to is a preposition and must be followed by a noun phrase, not a full clause.

Wrong: Owing to it was raining, we stayed inside.
正解: Owing to the rain, we stayed inside.

Hence is a conjunctive adverb, not a subordinating conjunction. It needs a semicolon or separate sentences.

Wrong: Hence we are busy, we cannot go.
正解: We are busy; hence, we cannot go.

Don't combine absolute adverbs with modal hedging; choose one for clarity.

Wrong: It is certainly maybe the best option.
正解: It might be the best option.

よくある質問 (6)

これらの単語の主な役割は、フォーマルな文脈で追加の補強情報や議論を加えることです。先行する文の主張を強化したり、拡張したりすることを示します。「その上さらに」というニュアンスで、より説得力を持たせる時に使います。
They indicate that what follows strengthens or expands upon a previous statement.
と覚えておきましょう。
はい、ほとんどの場合、moreoverとfurthermoreは互換性があります。どちらも同様に重要な点を追加する感覚を伝えます。furthermoreの方が少し強い、あるいは議論をさらに推し進めるニュアンスがあると感じる人もいますが、その違いは非常に微妙です。どちらを使っても大抵は問題ありません。
Yes, for the most part, moreover and furthermore are interchangeable.
「Owing to」は一般的に、出来事や状況の直接的な原因を指します(例:「owing to the storm」)。一方、「in view of」は、決定が下される際に考慮された要因を示します(例:「in view of new data」)。
はい、「owing to」はポジティブな原因にも使えますが、中立的またはネガティブな状況を説明する文脈でよく見られます。例えば、「The success was owing to their hard work」は完全に正しい表現です。
これらは、先行する文から生じる論理的な結果、結論、または適切な行動を正式に示します。高度な英語で明確で構造化された議論を作成するのに役立ちます。「The data was clear; hence, we made a decision.」
ほとんどの場合、はい、交換可能です。hencethusは両方とも直接的な論理的結論や結果を導入するため、多くのフォーマルな文脈でほぼ交換可能です。「The results were inconclusive; thus, more research is needed.」と「The results were inconclusive; hence, more research is needed.」はどちらも自然です。
