The word "marline" comes from Proto-Indo-European *mer-. It started in Proto-Germanic *mairōną. Then it appeared in Middle Dutch marlijn. Later, people used it in Middle Low German marling. After that, it was Middle English merlin.
A word passing through this many languages survived because it named something universally important.
