Forms

principal m or f (plural principais)[1] Medieval texts also write prinçipal; a letter of 1500 has primcipall.[2][3] A dialect form princepal was recorded in Portugal in 1970.[4]

Etymology

It is borrowed from Latin prīncipālis (“first, original; chief”), a learned word.[5][6][1][7] Houaiss and Cunha date it to the 13th century.[5][6] Houaiss and the OLD derive the Latin adjective from princeps (“first; chief, leader”) with the suffix -ālis, while Wiktionary derives it from prīncipium (“beginning”).[5][8][1] The OLD analyses the noun as prīmus (“first”) with the second element -ceps.[9]

The same Latin word is Galician principal, Spanish principal, Catalan principal, French principal, Italian principale and Romanian principal.[1] French has it from 1080.[10]

Earliest recorded meaning

R. Lorenzo's chronology cites the Crónica Geral on “one of the main things through which the Moors lost Valencia” (hũa das cousas principaes por que os mouros perderõ Valença) and the chronicle of 1344 on a causa principal “the main cause”; the Crónica Troiana has seys portas prinçipaes “six main gates”.[2] The first sense is “first in rank or importance, chief”.[2][5]

Semantic evolution

Bluteau (1712–1728) defines the adjective as what holds the first place among things or is most worthy of esteem, and records the noun o principal, the capital of a sum or debt as opposed to its interest.[11] Folqman (1755) has as pessoas principaes de huma Cidade for its leading citizens, and Morais (1789) adds the noblest or richest of a town, as in João de Barros, and the senior prelate of a patriarchal church.[12][13]

Later dictionaries add technical uses: the main clause of a sentence in grammar, the leading part of a symphony in music, and a heavenly body around which a satellite turns.[14][15][1] As a noun it names the superior of a religious community or a college, a chief, and in finance the principal of a loan.[16][15]
