headmistress

the word 'headmistress' is a transparent compound formed within english. the first element, 'head', derives from the old english term for the uppermost part of the body, which was extended metaphorically in middle english to mean 'leader' or 'chief'. the second element, 'mistress', entered english via old french, originating from the latin 'magister' meaning 'master' or 'teacher', with the feminine suffix '-ess' indicating a woman who holds such a role. when combined in the 19th century, the compound logically denotes the female chief teacher or principal of a school, paralleling the earlier formation 'headmaster'.
