Which meaning aligns with the root Dactyl-?

Explanation:
Dactyl- designates a finger or toe—the digits. It comes from Greek daktylos and shows up in terms like dactylitis (inflammation of a finger or toe) and polydactyly (having extra fingers or toes). It isn’t about the nail (that would be onych- or ung-), nor about a joint (that would be arthr-), and it isn’t limited to the thumb. So the meaning that aligns is finger, toe.
