IPA: /ˈwoʊfəli/
KK: /ˈwoʊfəli/
In a way that shows great sadness or regret; very badly or poorly.
The project was woefully underfunded, leading to its failure.
Woefully is formed from "woeful" (from Old English "wōeful", meaning full of woe or sorrow) and the suffix "-ly" (meaning in a manner of). The word "woefully" means in a manner that is full of sorrow or regret.
Think of being 'full of sorrow' ('woeful') and how the '-ly' makes it describe the way something is done. So, when you hear 'woefully', imagine doing something in a sorrowful manner.
