Other forms: reminded; reminds; reminding
To remind is to cause someone to remember, as when George Orwell writes, "The aim of a joke is not to degrade the human being, but to remind him that he is already degraded."
In remind, which appears in the early 17th century, the re-, of course, means "again," so the word can be thought of as "to mind again," or "think again," meaning to put something in someone's mind, to make them remember.
