What does endorsing mean?
"Endorsing" is the present participle of the verb "endorse," which has two principal uses in modern English. The dominant sense is to declare open support or approval for a person, product, idea, or course of action — celebrities endorsing brands, newspapers endorsing political candidates, or organizations endorsing reform proposals. The second sense is technical and financial: to endorse a cheque is to sign its reverse side, thereby authorizing its transfer or payment. A third, more formal use appears in law and official proceedings, where endorsing means ratifying or sanctioning a document. The word derives from the Latin "dorsum" (back), via Old French "endosser," reflecting its original meaning of writing on the back of a document. Because an endorsement puts the endorser's own credibility behind what is approved, the word carries connotations of public commitment and accountability rather than casual preference.

To endorse literally means to write on someone's "back" — the word comes from the Latin dorsum, the same root that gives us "dorsal fin."

Etymology of endorsing
"Endorsing" comes from the verb "endorse," which entered English in the late Middle Ages from Old French "endosser," meaning literally "to put on the back," formed from "en-" (on) plus "dos" (back), ultimately from Latin "dorsum." Its earliest English sense was precisely physical and bureaucratic: to write or sign on the back of a document, as with a cheque or a bill of exchange. From that concrete practice the meaning broadened figuratively to signify giving one's approval or backing to anything at all. Cognates sharing the same Latin root include "dorsal" and, through French "dos," the word "dossier" — itself originally a bundle of papers labelled on the back.

How endorsing is actually used
"Endorsing" carries a connotation of formal or public approval rather than private opinion — one endorses candidates, products, and proposals, often implying that the endorser's reputation lends weight to the thing approved. In banking contexts (especially British English), endorsing a cheque specifically means signing its reverse side. The spelling "indorsing" survives mainly in older American legal usage.
Easily confused with endorsing
"Indorse" is an older variant spelling of "endorse" still found in some legal contexts, but it refers to exactly the same act of signing or approving.
