/ˈwɛlɪŋk/(also wallink) Now rare
noun
Either of two water speedwells (genus Veronica): (a) British regional and Irish English (usually in form wellink) brooklime, V. beccabunga; (b) North American (usually in form wallink) American brooklime, V. americana.
Origin
Early 19th century. Probably the reflex of an apparently unattested compound from well + lemeke, with elision of medial -e- and assimilation of consonants in the second element.
