Joining together; bringing separate people or things together into one group or purpose.
From Latin 'unitus' (joined together), derived from 'unus' (one). The verb form adds the '-ing' suffix to describe the ongoing action of joining things into unity.
The phrase 'united nations' uses this word to describe separate countries acting as one, but linguistically it's interesting that 'unite' literally means 'make into one'—yet the UN actually emphasizes cooperation between many different entities.
