The act of appearing or becoming visible; an appearance or manifestation. A less common variant of 'apparition.'
From Latin 'apparatio' and 'apparere' (to appear). The word follows the pattern of Latin verbs becoming English nouns with the -tion suffix. It's closely related to 'apparatus' and 'apparition,' all sharing roots in 'apparere.'
This word is almost obsolete, but it reveals how English speakers once distinguished between the 'thing appearing' (apparition) and the 'act of appearing' (apparation). Languages gradually simplify by losing these tiny distinctions.
