The position, office, or authority of a headmaster; the term of service of a school's principal.
From 'headmaster' plus the noun suffix '-ship' (Old English '-scipe', indicating rank, office, or condition). The suffix also appears in 'friendship,' 'leadership,' and 'membership'.
The '-ship' suffix is one of English's most productive noun formers, turning nouns into abstract concepts of position or relationship—'headmastership' specifically emphasizes the authority and responsibility of the role.
The institutional role of 'headmaster' was historically male-exclusive. Women held equivalent leadership roles but under the gendered title 'headmistress,' reflecting institutional segregation in education administration.
Use 'school headship' or 'principalship' for gender-neutral reference; specify 'headmastership' and 'headmistressship' only when gender-segregated history is contextually relevant.
