Etymology: "Relenter" is a plain formation: the verb "relent" with the agent suffix "-er" added, so it names a person or thing that relents. The word "relent" itself came into English from Old French "relenter," meaning to slacken or soften, and it originally carried a sense of loosening or cooling, as in softening a hardened substance, before it came to mean giving up harshness or resistance. Adding "-er" to a verb in this way is one of English's most productive patterns, so the term is a transparent, everyday construction rather than a word with a dramatic backstory.
