apraxia

Definition

Total or partial loss of the ability to perform coordinated movements or manipulate objects in the absence of motor or sensory impairment; specifically, a disorder of motor planning.

Etymology

From Ancient Greek ἀπραξία (apraxía, “inaction”), from ἀ- (a-, “without”) + πρᾶξις (prâxis, “activity”) + -ία (-ía, abstract noun suffix). By surface analysis, a- + -praxia.

Example Sentences

• "But how does the skeptic live without knowledge or at least belief? It seems that the skeptical challenges, though theoretically unimpeachable, have objectionable practical consequences. Call this the apraxia problem for skepticism."
