Plural of “dwarf”

The plural of dwarf is dwarfs (some dictionaries also accept dwarves).

Why

"Dwarf" comes from Old English "dweorg," a native Germanic word for a small, often magical or mythological being found across old Germanic folklore. As a native -f noun, it could plausibly follow the -f-to-ves shift seen in "wolf" and "leaf," but modern standard usage has generally settled on the plain "dwarfs" as the more common and more broadly accepted plural, especially in scientific and everyday contexts.

J.R.R. Tolkien deliberately and famously chose "dwarves" over the more standard "dwarfs" in "The Hobbit" and "The Lord of the Rings," explicitly favoring the older, more folklore-resonant -ves ending to give his invented world a more archaic, mythic feel, and this literary choice has since significantly shaped popular fantasy-genre usage, where "dwarves" is now extremely common despite not being the traditionally dominant dictionary plural. Outside fantasy fiction, "dwarfs" remains the standard form in astronomy ("white dwarfs," "red dwarfs"), medicine, and general everyday usage describing a person of short stature.

Usage note

"Dwarfs" is the standard, dictionary-preferred plural in scientific, medical, and general everyday writing ("white dwarfs," "the dwarfs in the fairy tale"). "Dwarves" is widely accepted and even dominant specifically within fantasy fiction and gaming contexts, following Tolkien's influential precedent, but it remains a genre-specific convention rather than the standard general-English plural.

Tolkien himself acknowledged in his writing that "dwarves" was technically his own deliberate, non-standard spelling choice rather than an established form he was simply preserving, making this one of the rare, well-documented cases where a single influential author's stylistic preference measurably shifted an entire genre's everyday vocabulary. Medical and disability-advocacy writing increasingly favors "little people" or "people with dwarfism" over "dwarfs" as a person-first term in respectful contemporary usage, reserving "dwarfs" more for its scientific, astronomical, and folklore senses.

Common real mistakes

There's no single "wrong" answer between "dwarfs" and "dwarves" today, but writers should be aware of the genre and register distinction: using "dwarves" in a scientific astronomy paper about stars would look unusual, just as using the strictly clinical "dwarfs" in fantasy fiction would clash with genre convention. Writers describing real people should also be mindful of respectful, person-first language rather than defaulting automatically to either plural form.

The wider pattern

"Dwarf" is a rare case of a native -f noun where two competing plurals both remain fully alive today, split cleanly by genre and register rather than one form simply being more traditional or more modern, distinguishing it from words like "wolf" (fully converted to -ves) or "chief" (never converted at all).
