the word tumid originates from the latin adjective tumidus, meaning "swollen," which itself is derived from the verb tumēre, "to swell." this latin root can be traced back to the proto-indo-european base teuə-, tū-, meaning "to swell" or "to be strong," which also gave rise to words like tumor and thumb. the literal sense of physical swelling evolved naturally into the metaphorical sense describing language that is inflated or pompously overblown. the suffix -id, common in latin-derived adjectives, simply denotes the state of being swollen, whether literally or figuratively.

Structure: tum (swell) + id (adjective suffix) tum (from latin tumēre, meaning "to swell"); id (a latin-derived adjective-forming suffix, often indicating a state or condition).
