Having an apex; coming to a point or peak at the top.
From Latin 'apex' (summit, peak) + English past participle suffix '-ed'. While not commonly used, it follows standard English verb-to-adjective conversion patterns.
Although rare in modern usage, 'apexed' reminds us that English speakers can theoretically turn almost any noun into an adjective with '-ed'—we could say 'an apexed roof' though 'peaked' or 'pointed' sound more natural.
