Etymology: < French digitigrade (1805 in Cuvier as adjective and noun) < classical Latin digitus finger (see digit n. and adj.) + -gradus -grade comb. form. Compare scientific Latin Digitigrada, former tribe name (1817 in Cuvier).

Chiefly Zoology.

A. adj.

That walks on the toes; adapted for or designating such a manner of walking. Also formerly: †of, relating to, or designating the former tribe Digitigrada of carnivorous mammals, including dogs, cats, mongooses, weasels, etc., whose members walk on their toes (obsolete). Cf. plantigrade adj. 1a.

1833 Penny Cycl. I. 4 The legs also are completely digitigrade; that is to say, the heel is elevated, and does not come into contact with the surface... Digitigrade animals, which tread only upon the toes..have much longer legs than plantigrade animals.

1873 Proc. Amer. Philos. Soc. 13 199 The inner malleolus is entirely without the groove for the tendon of the tibialis posticus muscle, and therefore different from many of the digitigrade Carnivora.

1951 G. R. de Beer Vertebr. Zool. (ed. 2) xxii. 275 Animals..like the dog, rest only the under surface of the fingers and toes on the ground, while the palm of the hand and sole of the foot take no share in bearing the animal's weight. This is the digitigrade condition.

1973 Nature 10 Aug. 374/2 The low brachial index of D[ryopithecus] africanus suggests that it was not adapted for either fast digitigrade running or habitual arm-swinging.

2006 S. M. Stirling Sky People v. 111 A good deal of its length was the powerful digitigrade legs, each with a great sickle-shaped claw held up against the hock.

B. n.

A digitigrade animal; a creature that walks on its toes. Formerly spec.: †any animal of the former tribe Digitigrada (obsolete).
