igualmente
/iˌɡwalˈmente/ · B1 · adv
likewise
⚖️ igual + -mente = equal + -ly, so equally; also a reply: same to you
Igual comes from Latin aequalis, the same root as English equal. The ending -mente turns an adjective into an adverb, like English -ly. When someone says mucho gusto or buen viaje, answering igualmente means likewise, or the same to you.
