An arrangement of two or more objects or persons one behind another, or working together in close cooperation.

Tandem emphasizes a highly synchronized, step-by-step partnership where two entities act as a single unit, one directly supporting or following the other.

The story behind the word. In Latin, 'tandem' was an adverb meaning 'at length' or 'at last' (referring to time). In 18th-century England, university students humorously applied the word to a carriage drawn by two horses harnessed one in front of the other (lengthwise) rather than side-by-side, playing on the 'length' of the setup.
