Etymology: "Altitudinal" is simply "altitude" with the adjective-making ending "-al" added, and "altitude" itself is the older word underneath. It is built on Latin "altitudo," meaning "height," which came from "altus," "high" or "deep," joined to the noun-forming ending "-tudo." English took the Latin route through "altitudinis," the stem form used before endings, so the adjective carries a Latin shape even though it was formed in English. The word is a straightforward derivation rather than a coinage with a dramatic backstory. Its meaning stays close to its roots: something that concerns how high a thing is, whether a measured elevation above sea level or a particular height band. Latin "altus" is an interesting word in its own right, since it could mean high or deep depending on context, which is a reminder that vertical measurement was never fixed in one direction.
