Serpent Ser"pent, n. [F., fr. L. serpens, -entis (sc. bestia), fr. serpens, p. pr. of serpere to creep; akin to Gr. ???, Skr. sarp, and perhaps to L. repere, E. reptile. Cf. {Herpes}.] 1. (Zo["o]l.)

Many species glide swiftly over the ground, some burrow in the earth, others live in trees. A few are entirely aquatic, and swim rapidly. See {Ophidia}, and {Fang}. [1913 Webster]
