For various reasons, English is a Global language in today’s world. It has become a common language of communication, bringing countries closer and establishing economic globalization. However, there are various ways in which this language is used, as is common with most civilized languages. These rules are now more pronounced since English has been informally established as the common bridge to close gaps.

There is not much difference between Business English and Regular English.  Business is more formal and contains certain technical words or jargon that people do not generally use while speaking, as it might sound too rigid. With Regular English, one does not stick strictly to formality. 

Characteristic differences between Business English and Regular English:

• No slang is allowed in Business English.
  A few slang terms may be used depending on the situation. E.g., “Waz up dawg!”
• Formal acknowledgment is required in Business English. E.g., “Thank you very much, or appreciate it.”
  Acknowledgment can be informal in Regular English.  E.g. – “Thanks, or Cool, or Cheers.”
• Tone and expressions are more polite in Business English. E.g. – “How are you doing?”
  Tone and expressions may vary depending on whom one is speaking to. For example – The tone of speaking to relatives will be vastly different from speaking with friends.  E.g.- “Howz it going?”
• The usage of difficult and appropriate words, jargon, and idioms is common in Business English. E.g.- ASAP, leverage, perhaps, possibility etc.
  Words are more free-flowing and expressions are more casual keeping the conversation more informal in Regular English. E.g.- so, maybe, point out, let’s see, etc.
• Full forms of expressions are generally used in Business English – I will against I’ll or Want to go against Wanna go.
  Shorter forms of expressions are usually used in Regular English – I’ll against I will or Wanna go against Want to go.  

Purposes of Business English and Regular English: 

• Business English is used to facilitate communication in professional settings, like meetings, emails, presentations, or negotiations. The goal is often to persuade, inform, or make decisions.
• Regular English is used in everyday conversations, personal communication, or informal contexts. It is more about expressing thoughts, feelings, and ideas casually.

As you must have derived from the above, grammar is maintained in both cases, but the way of speaking and choice of words vastly change from situation to situation. Also, it changes according to the people to whom they are being spoken to. It is to be noted that each industry has its own set of jargon and language preferences. These might not make much sense to those using Regular English, but they are of importance to people connected with those industries. Keeping these in mind will help anyone to communicate in a better way.
