(originally in stories by J. R. R. Tolkien) a member of an imaginary race of small people

Bilbo Baggins lived until age 131, making him the second oldest halfling of all time

(in fantasy fiction) a being who is the offspring of a human and a member of another race

sometimes Ana wondered whether he might be a halfling like her, with a human father and elf mother

a person who is not yet fully grown

in this service he remained until he was nineteen, still serving in the capacity of halfling, with only a halfling's fee
