Major is a rank of commissioned officer, with corresponding ranks existing in many military forces. It is also used in some police forces such as the New York State Police, New Jersey State Police and several others.

When used unhyphenated, in conjunction with no other indicator of rank, the term refers to the rank just senior to that of an army captain and just below the rank of lieutenant colonel. It is considered the most junior of the field ranks. In some militaries, notably France, the rank is referred to as commandant, while in others it is known as captain-major. It is also used in some police forces and other paramilitary rank structures.

When used in hyphenated or combined fashion, the term can also imply seniority at other levels of rank, including general-major or major general, denoting a mid-level general officer, and sergeant major, denoting the most senior NCO of a military unit.

It can also be used with a hyphen to denote the leader of a military band such as in pipe-major or drum-major.

A company is a business organization. It is an association or collection of individual real persons and/or other companies, who each provide some form of capital. This group has a common purpose or focus and an aim of gaining profits. This collection, group or association of persons can be made to exist in law and then a company is itself considered a "legal person". The name company arose because, at least originally, it represented or was owned by more than one real or legal person.

In the United States, a company may be a "corporation, partnership, association, joint-stock company, trust, fund, or organized group of persons, whether incorporated or not, and (in an official capacity) any receiver, trustee in bankruptcy, or similar official, or liquidating agent, for any of the foregoing." In the US, a company is not necessarily a corporation.

In English law and in the Commonwealth realms a company is a body corporate or corporation company registered under the Companies Acts or similar legislation. It does not include a partnership or any other unincorporated group of persons, although such an entity may be loosely described as a company.
