What does tandem mean?
Tandem describes people, organizations, or things that are linked, arranged one behind another, or working in close coordination. The familiar phrase “in tandem” means together or in cooperation, often implying that the participants’ actions are closely coordinated. Tandem can also function as an adjective, as in “tandem efforts” or “a tandem campaign,” and as a noun for a bicycle built for two riders seated one behind the other. The word may additionally refer to two people or units arranged in succession. Its associations are generally positive: it conveys partnership, efficiency, shared purpose, and synchronized action. Although the bicycle remains the most immediately recognizable concrete use, the figurative sense is especially common in business, politics, science, and everyday descriptions of people working together.
A bicycle with two seats and two sets of pedals, one behind the other; more broadly, a pair of people or units arranged in succession or working together.

Where does tandem come from?
English borrowed tandem in the early 17th century from the Latin adverb tandem, meaning “at the same time” or “in succession.” The Latin word was based on tam, meaning “so much,” together with the pronominal suffix -dem. Its development from an idea of simultaneity or succession to its modern sense of paired or coordinated activity followed through the use of tandem bicycle and, later, figurative expressions such as “in tandem.”
How tandem is actually used
