More elegant; a comparative form indicating greater refinement, grace, or tasteful quality than something else.
From elegant (Latin elegans) plus the comparative suffix -er, which forms comparative adjectives in English. The ending -er replaces or modifies the base to show comparison between two things.
Adding -er to make comparatives is so old it goes back to Old English, but it only works with one-syllable adjectives and some two-syllable ones—which is why 'eleganter' sounds a bit archaic and formal to modern ears.
