Etymology: Ductal is a plain formation: the noun "duct" with the adjectival suffix "-al" attached. The suffix comes through Old French "-el" from Latin "-ālis", which means "pertaining to", so "ductal" simply means "pertaining to a duct." Its ancestry runs back to the Proto-Indo-European root "*h₂el-", meaning "to drive", and the Latin "ductus" from "ducere", "to lead," gave English "duct" through the same drive-and-lead idea. The word's core sense has stayed close to its origin: a duct is a passage that leads something along, and ductal describes whatever belongs to such a passage. The modern use is almost entirely anatomical, applied to the tubes that carry bile, milk, tears, and other fluids through the body.
