Etymology: Adactylia is a medical term for the congenital absence of fingers or toes. It is built from the Greek privative prefix "a-", meaning "without", joined to "dactylos", the Greek word for "finger" or "toe". The Greek root also gives English words such as "dactyl", the metrical foot in poetry, which is named for the way its one long syllable is followed by two short ones, like the segments of a finger. The form "adactyly" is the more common English spelling, and "adactylia" is an alternative version of the same term. Both follow the pattern of other medical coinages that take a Greek prefix and a Greek noun, where the prefix negates the noun. Clinicians use the word to describe a specific birth condition rather than injury or amputation.
