Apertural |ˈ apətʃər(ə)l | adjective


Astro-English: from Astronese, the word aperture is used in the context of the Astroeschatology to mean “lifespan” due to the general use of the word aperture denoting “an opening”; in Astronism, this is applied to the context of scope to denote a person’s lifespan in relation to the opportunities presented to them during their aperture.
