The word company originally taken from the Late Latin word companio “companion, one who eats bread with you”,.

To join efforts together with the people you agree with. (People who share the same interests, working towards a certain aim or goal).

Company members share a common purpose and unite in order to focus their various talents and organize their collectively available skills or resources to achieve specific, declared goals. 

<The coming together of two or more people, who have decided to create an environment of intimacy, for the sake of bringing to reality their declared goals>

Companies take various forms such as:

Voluntary associations which may be registered as a Nonprofit organization
A group of soldiers
Business entity with an aim of gaining a profit 
Financial entities and Banks

A company or association of persons can be created at law as legal person, so that the company is itself can accept Limited liability for civil responsibility and taxation incurred as members perform (or fail) to discharge their duty within the publicly declared “birth certificate” or published policy.

Because companies are legal persons, they also may associate and register themselves as companies – often known as a Corporate group. 

When the company closes it may need a “death certificate” to avoid further legal obligations.
