regrettably
UK: /rɪˈɡretəbli/ | US: /rɪˈɡretəbli/
adv. in a manner that inspires regret or disappointment
adv. unfortunately (used to express apology or disappointment)
The word "regrettably" combines "regret," derived from Old French regreter (to lament, feel sorrow), with the adverbial suffix "-ably," from Latin -abilis (capable of). "Regret" originally implied grief or longing, evolving into its modern sense of remorse. The suffix "-ably" transforms the adjective "regrettable" into an adverb, emphasizing the manner of an action. The word's structure reflects a logical progression: "regret" (core emotion) + "-ably" (mode of expression).
