Other forms: wormwoods
Use the noun wormwood to describe a strong-smelling, shrubby plant of the genus Artemisia.
The form of this word that designates an aromatic shrub is probably influenced by folk etymology, since neither worms nor wood have much to do with the plant: in Old English it is wermod. Among other uses, it is the primary flavoring in the absinthe, and sometimes in vermouth: a word with a similar sound and a common ancestor.
