Definitions

Etymology: "Whirm" appears in dialect and older English as a variant of "whirr" and "whirl," meaning to spin or move rapidly with a humming or buzzing sound. It is most likely imitative, like "whir," with the "-m" ending shaped by the same sound-symbolic pattern that gives words like "hum" and "boom" their rumbling quality. Its exact early attestations and regional spread are uncertain, so the precise date of its first recorded use is not something I can confirm.

Synonyms: whirl, spin, twirl
