Empresa

Empresa
 

Ways of sayng empresa in English and when do we used them for example company?
Enterprise?
Etc...

There might be a big variation between BrE and AmE, but for the UK, empresa = company, firm, business, etc.

The differences are not very clear.

A company usually makes something, manufactures something.
A limited company (Ltd.) = S.A.

Fred and John formed a company for the production of rubber ducks

A firm can be a company, but includes e.g. lawyers and accountants

Fred and John work in a firm of solicitors.

Fred and John formed a business partnership to sell drinking holidays in Iran.

Any use?

The AmE is pretty much spot on to what Perikles said.

whaat about those created by the administration or government?

They don't exist

Yes they do. A British example would be the Student Loans Company (which is a PLC).

Just out of curiosity, who owned the British East India Company? :confused:

It was formed by Royal Charter in 1600 according to Wiki, and there were shareholders who 'owned' it, I suppose.

Public sector firm
Security firm ( no lawyers involved)
What about enterprise?

A security firm would be hiring out people for security purposes. I don't really know the technical difference between the other two. An enterprise might not be a business, legally. :thinking:

Also, public sector company, but not firm. To me, a firm is something which professionals do, but don't produce anything. Like lawyers.

@Perikles: Thank you. I always thought it was property of the British government. :)
