10 Commonly Used English Abbreviations in Business Situations 236

English was once the preserve of a select few.
It was a language used only in teams that communicated directly with foreign countries, such as trade, overseas sales, and global business departments.
But now, English has become an essential tool that has naturally permeated the work of all office workers.
From sending an email, saying something in a meeting, to sharing a short sentence, we use English "as if it were business."

Moreover, AI tools, including ChatGPT, play a major role these days.
Because it lets you translate and polish sentences, and even create email drafts, with ease.
But no matter how much technology advances, there are still things that only humans can do.
It is the sense of judging and using appropriate expressions within the context of work.

Working in English isn't just about being able to construct sentences.
It's about choosing your words appropriately for the situation, adjusting nuance, and expressing yourself with consideration for the other person's position.
Without the experience of developing this kind of sensitivity in the real world, there are limits to the areas where AI can help.
The reason many people struggle with English isn't because they lack the skills, but because they haven't experienced how English is used within a company.

The author of this book has worked with international colleagues for over 20 years, using English not just as a language but as a "work tool."
I've been repeating the routine of writing emails in English in the morning, exchanging opinions in meetings in the afternoon, and having short conversations in the evening.
The conclusion I reached through such physical contact is simple but powerful.
English is not a skill to be learned separately, but rather a work ethic that is acquired through work.

This book does not teach grammar or conversational expressions.
Instead, we've included practical English that works in the workplace, tips for changing the flow of a conversation with a single word, and tips for avoiding misunderstandings with a single, short sentence. We especially recommend this to those who:

ㆍ Those who have received a job offer from a foreign company but are hesitant due to lack of confidence in English
ㆍ Someone who can speak basic English, but has difficulty speaking in business situations.
ㆍ Someone who knows that even though they receive help from AI, the final decision is always 'theirs'

The English you actually encounter at work is different from the English used on exams.
The ability to accurately convey the main point is far more important than flowing sentences, and practicality is a greater strength than fluency.
Moreover, most of my foreign colleagues do not speak English perfectly.
English is a global communication tool, not a stage for competing for perfection.

This book reflects that reality, and contains only expressions that can be applied immediately in real life, without unnecessary explanation.
Whether you need to speak up in a meeting, report to a foreign boss, or resolve disagreements via email, this book will serve as your reliable backup.

What we need now isn't more study, but a single sentence that has been tested in the field. I've compiled all of those sentences in this book.
Now, it's time to make English a natural part of your work.
