IPA: /ˈpɛniˌrɔɪəl/
KK: /ˈpɛnɪˌrɔɪəl/
A type of mint plant known for its aromatic leaves and flowers, often used for its oil in traditional medicine and as an insect repellent.
She brewed a tea from pennyroyal leaves to help with her stomachache.
Pennyroyal is derived from the Middle English 'pennyrial' (meaning a type of mint) and the Old French 'pennroyal' (meaning mint). The word combines 'penny' (possibly referring to the small size of the leaves) and 'royal' (meaning regal or of high quality). Thus, pennyroyal refers to a mint that is considered of high quality or value.
Think of 'penny' as something small and 'royal' as something of high quality — pennyroyal is a mint that is both small and valued.
