-elect

This usage of the term -elect originated in the Catholic Church, where bishops were elected but would not take office until ordained.

[4] By the 19th century, the term had expanded to describe any position in which a substantial period elapses between election and installation.

The advantage of this schema is a clear continuity of succession, as well as the opportunity to familiarize the president-elect with the operations of the organization before becoming president.

For example, if an election for president was held in January, but the term of office does not begin until March, the person who was elected president may be called "president-elect" but does not hold any power until the term begins in March.

Similarly, organizations may have other official positions such as vice president-elect, secretary-treasurer-elect, director-elect, and chair-elect.
