[Middle English, alteration of Old French principe, from Latin prīncipium, from prīnceps, prīncip-, leader, emperor.]

Word History: Despite generations of spelling lessons, the words principle and principal are still commonly confused. Perhaps an understanding of their history will help in keeping them straight. Both words go back to the same Latin word, prīnceps, meaning "first, as in time, position, or authority." The split that has caused all the trouble occurred in the next stage of development. From prīnceps were derived the noun prīncipium,"start, origin, guiding principle," the adjective prīncipālis,"first in importance or esteem," and the noun prīncipālis,"a leading citizen." Clearly the latter two words with the ā between the p and the l have given us the adjective principal (first recorded around 1300) and the noun principal (also first recorded in a work composed around 1300). Perhaps it should not be mentioned that one Middle English spelling for the noun was principle. On the other hand, the Latin word prīncipium and its Old French descendant principe were involved in the creation of the word principle in Middle English, first recorded in a work written around 1380. Words like manciple and participle influenced the spelling of this new word, but again perhaps we should keep silent about the fact that we also find the word spelled principal and prinsipal in Middle English. A key point to remember about these seemingly aberrant Middle English spellings is that in Middle English spelling was not nearly as fixed as it usually is today, a development that was much furthered by the invention of printing. When we interchange spellings for principle and principal, we are doing something that would have been less of a fault in the days before the conformity imposed on us by this marvelous invention.
