the.com/high commissioner

means The senior diplomat one Commonwealth country sends to represent it in another Commonwealth country, doing everything an ambassador does but under a gentler title.

from Comes from 'commissioner,' someone formally entrusted with a commission — a task delegated by authority — rooted in Latin 'committere,' to entrust or join together. The 'high' was added to mark seniority, the top commissioner among lesser ones. The title took its modern diplomatic sense as the British Empire loosened into the Commonwealth: member nations weren't foreign states to one another in the old sense, so 'ambassador,' with its implication of separate sovereign powers, felt wrong. 'High commissioner' let everyone keep the full rank and ceremony of an ambassador while preserving the fiction — or the fact — of family.
