Forms: 1800s– perissodactyl, 1800s– perissodactyle. Also with capital initial.

Origin: A borrowing from Greek. Etymon: Greek περισσοδάκτυλος.

Etymology: < Byzantine Greek περισσοδάκτυλος (see note) < ancient Greek περισσός uneven, odd (see perissad adj. and n.) + -δακτυλος -dactyl comb. form (compare quot. 1848² at sense A.). Compare scientific Latin Perissodactyla , suborder (now order) name (R. Owen 1848, in Q. Jrnl. Geol. Soc. 4 131), and French périssodactyle (1848). Compare artiodactyl adj., artiodactyl n.Byzantine Greek περισσοδάκτυλος is glossed by R. Owen (in the source of quot. 1848¹ at sense A.) as ‘qui digitos habet impares numero’ having an odd number of fingers or toes. Liddell and Scott's Greek-Eng. Lexicon (ed. 9, 1940) glosses the word as ‘with more than the usual number of fingers or toes’, but in the Revised Supplement (1996) this has been amended to ‘having toes of unequal length, of a hen’.
