A dryad (/ˈdraɪ.æd/; Greek: Δρυάδες, sing.: Δρυάς) is a tree nymph, or female tree spirit, in Greek mythology. In Greek drys signifies “oak.” Thus, dryads are specifically the nymphs of oak trees, though the term has come to be used for all tree nymphs in general. (Nancy Ford Cones - Women in a forest, c.1925)
