the adverb "supremely" is formed by adding the old english adverbial suffix "-ly" to the adjective "supreme." the adjective traces back to latin supremus, the superlative of superus (meaning "that is above"), which itself derives from the preposition super (over, above). this progression from a spatial concept of being physically above to a metaphorical state of being highest in quality or authority illustrates a common semantic shift. thus, "supremely" literally carries the sense of "in a manner that is the highest or above all others."

Structure: supreme (highest) + ly (adverb suffix) - supreme: from latin supremus, the superlative form of superus (situated above, high). it functions as the root adjective meaning "highest in rank or degree". - ly: from old english -līce, an adverbial suffix used to form adverbs from adjectives, indicating manner or degree.
