Paying attention to the vowel sound is key. The a in plank makes it sound more open and sharp, while the u in plunk gives it a duller tone, much like the sound it imitates.
Origin and Etymology
Plank comes from the Old French word planke and the Latin planca, meaning flat board. It has been used in English since the 13th century to describe wooden boards used in building and ship construction.
Plunk, on the other hand, originated in the 19th century as an imitative sound word in American English. It mimics the sound made when something falls into water or hits a surface. Over time, it gained metaphorical meanings, such as sitting down heavily or playing simple tunes on an instrument.
