adan is Sindarin for a "Man" (i.e., as opposed to Elf, Dwarf, Hobbit, etc.). The plural is Edain. Properly, this word refers only to those Men who are descended from the Three Houses of Elf-friends.

The term often appears as an element of other words, notably Dúnadan (Man of the West, Numenorean) and Elladan (Elf-man, referring to his Half-Elven heritage).
