Origin of primary

  • Middle English from Latin prīmārius chief from prīmus first per1 in Indo-European roots

    From American Heritage Dictionary of the English Language, 5th Edition

  • Borrowing from Latin prÄ«mārius ("of the first", “of the first rank", “chief", “principal", “excellent"), from prÄ«mus (“first"; whence the English adjective prime) + -ārius (whence the English suffix -ary); compare the French primaire, primer, and premier.
