distrikto

A drawn boundary, not a lived-in one. Distrikto is an administrative unit: something a government drew on a map and attached powers to. That is what separates it from its neighbours, and the four of them make a usable fence. Regiono is a region in the loose geographical sense, with no official status implied. Provinco is a province, a large formal division of a country. Kvartalo is a quarter or neighbourhood of a town, defined by how it feels rather than by where the boundary runs: the old quarter, the Chinese quarter. And distrikto is the one with paperwork. Electoral districts, police districts and school districts are all distriktoj.

The false seam, and it has two layers. Dis- is a real Esperanto prefix meaning apart or in different directions, as in disdoni (to distribute) and disiri (to disperse), so distrikto invites the reading dis- plus some root trikt-. There is no such root. And there is no suffix -ikt- either, which is the second reading a learner sometimes tries. The word came from Latin in one piece.

Nor is it built on distri, to distract, despite the shared four letters. That one is from distrahere, to drag apart; this one is from distringere, to draw apart. Both have Latin's dis- inside them, which is genuinely the ancestor of Esperanto's prefix, but neither is decomposable in Esperanto and treating them as related will not help you remember either.
