Etymology
the word 'horizontally' traces its lineage to the ancient greek concept of a boundary, specifically the 'horizōn kyklos' or 'limiting circle' that divided the visible earth from the sky. this root, 'horizōn', passed into latin as 'horizont-' and entered english to denote the apparent line where earth meets sky. the addition of the latin-derived adjectival suffix '-tal' created 'horizontal', describing anything parallel to this foundational line of reference. finally, the old english adverbial suffix '-ly' was appended, transforming it into 'horizontally', an adverb precisely describing motion or orientation parallel to that fundamental earthly plane.
