Etymology: "Basal" is a plain English formation: the noun "base" with the adjectival suffix "-al" attached. "Base" came into English in the Middle Ages by way of Old French, and it traces back to Ancient Greek "basis", meaning a step, a pedestal, or the foundation on which something stands, drawn from a Greek verb for going or stepping. The Greek noun passed into Latin as "basis" and from there into English as well, so the two words share a root. The suffix does the adjectival work. Latin "-alis" gave English "-al," which turns a noun into a word meaning "relating to" that noun, as in "national" or "musical." "Basal" therefore means relating to a base, and in technical use it is most often applied to the lowest layer or fundamental level of something, such as basal metabolism or the basal layer of skin.
