escollo

reef, shoal; pitfall, stumbling block

“El principal escollo es el confinamiento perimetral, que se establece para todas las comunidades, excepto los archipiélagos (Canarias y Baleares).” — The main stumbling rock is the perimeter lockdown, which is established for all the [autonomous] communities, except the archipelagos (the Canaries and Balearics).

Borrowed from Italian scoglio, from Vulgar Latin *scoculum (possibly through a Gallo-Italic intermediate), from Latin scopulus, from Ancient Greek σκόπελος (skópelos, “lookout place: hence peak, headland, promontory”). Compare Catalan escull.
