Forms

base f (plural bases)[1]

Etymology

It is borrowed from Latin basis (“base, pedestal, foundation”), which is from Ancient Greek βάσις (básis, “step; that on which one stands, base”).[2][3][4][1] The Greek word is a noun of βαίνω (baínō, “to walk, step”);[1][5][6] Wiktionary traces it through *gʷə́tis to *gʷémtis, from the root *gʷem- (“to step, come”), the root of Latin veniō (“to come”).[1][5][6]

Corominas dates the word only from 1709 and says that until the 17th century Spanish used the form basa for all its modern senses; the Latinising form appeared first as a term of mathematics and physics and gradually took over, leaving the older one with the sense “base of a column or statue”.[2][3] Between the 16th and 18th centuries the unadapted Latin form was also used in Spanish.[2] The corpus of the Academy and the dictionary of Alfonso X's prose, however, have the plural bases for the base of a column in Alfonso X's General Estoria of about 1275.[7][8][9] The cognate French base is recorded from about 1160.[6]

Earliest recorded meaning

In the General Estoria (c. 1275), Alfonso X's translation of the description of the Tabernacle, the boards stand on bases with sockets: E fiziéronles en los assentamientos de los bases a cada tabla dos logares fechos como quiciales “and in the seats of the bases they made two places like sockets for each board”.[7][8] The DPCAX already gives the two senses “main foundation or support” and “base of a column or statue”.[8]

Semantic evolution

The word stayed rare until the 18th century, when Corominas finds it established as a technical term.[2] The Autoridades (1726) treats it as a term of geometry, the line or surface on which a figure rests, and adds terms of optics and statics.[10] In the Academy's 1817 dictionary it is still marked as a term of mathematics.[11] Records from Lima of 1791 use it for the base of a triangle and, in chemistry, for the base of sea salt.[12]

Since then the word has spread to almost every field: the foundation or main support of anything, a military base, the rank and file that a leader represents, the rules of a competition, a base in baseball, and technical senses in grammar, economics, chemistry and mathematics.[4][1] The verb basar “to base” followed in 1873.[3][2] In several countries of the Americas base also means a perm, the artificial waving of the hair, and in Ecuador and Bolivia a crude cocaine paste.[13]
