Etymology
In English, this muscle’s name is the muscle that leads the big toe away (from the other toes). Abductor is a term that describes the function or action of the muscle. It literally means to draw or to lead away from and is derived from the Latin ab meaning “away from” and ducere meaning “to lead or to draw.” The term hallucis is from the Latin hallux, which originally arose from the Greek halmos meaning “to leap or spring.” The big toe was so-named because of its functional role in leaping.
Origin
Flexor retinaculum, the medial aspect of the calcaneal tuberosity, and the plantar aponeurosis.

Action
Abduction of big toe; important role in deepening the longitudinal plantar arch when pushing off the ground with the toes (as in walking).
