Etymology: "Remiss" comes from Latin "remissus," meaning "languid" or "negligent," which is the past participle of "remittere," a verb that literally means "to send back" or "to let go." The idea of letting something slacken is what links the Latin sense to the modern one: someone who lets their duties go slack is careless about them. The word reached English in Middle English, where spellings such as "remisse" and "remysse" appear. Over the centuries its sense narrowed from general slackness or lack of energy toward a specific failure to perform one's obligations, which is how it is used today: a remiss official or a remiss parent is one who has neglected a responsibility.
