What does monodactylous mean?
Monodactylous is a specialized English adjective meaning that something has only one digit, such as a single finger or toe, on each limb. Its clearest use is in zoology, anatomy, and paleontology, where researchers describe animals, fossil creatures, or individual limbs according to the number of digits they possess. A monodactylous limb therefore differs from a normal hand or foot with several digits rather than merely having one digit placed unusually. The word can also characterize an entire animal whose limbs each bear a single digit. In ordinary conversation, a plainer expression such as one-toed or single-toed would usually be clearer. Monodactylous is nevertheless useful in specialist writing because it precisely and compactly identifies a particular anatomical condition. Its combination of Greek elements also makes it a recognizable member of the family of English words involving dactyl and the combining form mono-, although its modern meaning is far more specific than those related forms.
