the.com/pointed arch

means An arch made of two curved sides that meet at a peak instead of a single round curve, used to span openings and channel weight downward and outward into supports.

from The form rose to prominence in Gothic architecture, likely developed from overlapping round arches (a technique seen earlier in Islamic architecture, including structures like the Great Mosque of Córdoba) and refined by medieval European builders — the English term 'pointed arch' is simply descriptive, while the style itself was later dubbed 'Gothic' by Renaissance critics who meant it as an insult, blaming the 'barbarian' Goths for what they saw as a lapse from classical taste.
