Merriam-Webster's Word of the Day for January 29, 2026 is:
reciprocate \rih-SIP-ruh-kayt\ verb
To reciprocate is to do something for or to someone who has done something similar for or to you. Reciprocate can also mean “to have (a feeling) for someone who has the same feeling for you.”
// It was kind of my friend to give me a ride to the airport, and on the flight I was thinking of how to reciprocate the favor.
“She entered the post office and greeted Tommaso, who reciprocated with a smile, then Carmine, who stroked his beard and shot her the usual skeptical glance.” — Francesca Giannone, The Letter Carrier (translated by Elettra Pauletto), 2025
Did you know?
“Scratch my back and I’ll scratch yours,” “do unto others as you would have them do to you,” “share and share alike”: such is the essence of the verb reciprocate, which implies a mutual or equivalent exchange or a paying back of what one has received. Reciprocate traces back to the Latin verb reciprocare (“to move back and forth”), which in turn comes from the adjective reciprocus, meaning “returning the same way” or “alternating.” Indeed, one of the meanings of reciprocate is “to move forward and backward alternately,” as in “a reciprocating saw.” Most often, however, reciprocate is used for the action of returning something in kind or degree, whether that be a gift, favor, or feeling.
