Please let me know should we use an article (a, the) before Business (noun). Please find the example sentences and let me know your valuable feedback.
Examples:
It goes into business as well.
He is running business.
Or these should be like this:
It goes into a business as well.
He is running a business.
Thanks in advance.
Where "business" is being used in a similar context to "company" or "organisation", and as such is countable, you need to make sure you use an article.
It goes into the business as well. He is running a business.
Or:
He has been running the business since day one.
So both of your phrases above require an article.
However, the term "business" can also be used as a concept, describing trade (see its various definitions). In this case it is an uncountable (conceptual) noun, and so no article is needed.
Business is going well at Blah Blah Blah Inc's Headquarters.
Business can be used as either a countable noun or an uncountable noun.
Your examples should be written,
It goes into business as well.
He is running a business.
As I said once in another answer of mine, most dictionaries give the definitions without saying anything about a noun being countable or uncountable. However, some dictionaries do. To check the countability of a noun online, I recommend Macmillan Dictionary and Collins Dictionaries.
You can consult, for example, Macmillan about the word business.
