vertically
UK: ˈvɜːtɪkli | US: ˈvɜːrtɪkli
adv. in a vertical direction or position
adv. in a way that is aligned with the direction of gravity
The word "vertically" derives from the Latin "vertex" (meaning "highest point" or "summit"), combined with the adjectival suffix "-al" (forming "vertical"—relating to the upward direction). The adverb suffix "-ly" was later added in Middle English to indicate manner. The progression reflects a logical shift from the concept of a peak ("vertex") to alignment with an upward/downward axis ("vertical"), and finally to the adverbial form describing such alignment ("vertically").
