What is the difference between an alliance and a partnership?

Answer 1

The term alliance is more usually applied to political arrangements; two or more nations form alliances by way of treaties, such as NATO, the North Atlantic Treaty Organization. The term partnership is more often applied to business arrangements. If two people run and own a business together, they are business partners and can be said to have a partnership. Marriage is more usually considered to be a partnership than an alliance, and when it is described as an alliance, it is usually because it is seen more as the marriage of two extended families, rather than just the marriage of two people (so a large family group is in some sense like a nation, and can form alliances). But bear in mind that it is perfectly possible to describe two nations as partners, or two people as allies. The terms are largely interchangeable.
