Etymology
Origin of endorse
First recorded in 1350–1400; variant (with en- for in- ) of earlier indorse, from Medieval Latin indorsāre “to endorse,” equivalent to Latin in- in- 2 + -dorsāre, derivative of dorsum “back”; replacing endoss, Middle English endossen, from Old French endosser, equivalent to en- en- 1 + -dosser, derivative of dos, from Latin dorsum
Explanation
To endorse is to give support to someone or something. "I endorse this!" means "I think this is a good thing, and so should you." People endorse in many ways. When someone endorses a politician, it means "You should vote for this person, and I'm putting my reputation on the line to say so." When someone endorses a product in a commercial, it means "Go buy this! You'll like it." To endorse is to give support. You can also endorse a check, which means writing your name or someone else's on the back so that you or the other person can cash or deposit it.
