Etymology: "Filler" is a simple formation: the verb "fill" plus the agent suffix "-er," meaning one who or that which fills. "Fill" itself goes back to Old English "fyllan," a verb built on the adjective "full," and both trace to a Proto-Germanic root "*fullaz" that has been reconstructed from a much older Indo-European base. The word's history in English is therefore plain: "filler" is a native English compound-style derivation, not a borrowing. The suffix has a longer journey than the word. The "-er" ending descends from Latin "-arius," which passed through Old French "-ier" and reached Middle English as "-er," and it has worked its way into countless English nouns for people and tools, such as "baker" and "hammer." Attaching it to "fill" gave the sense of a thing whose job is to fill a gap, which is how the word came to describe materials used to plug holes, cracks, and voids.

Synonyms: stuffers, plug-ins
