Translation guide
The English adverb 'furiously' can express intense anger, energetic speed, or frantic effort. Japanese uses different adverbs and phrases depending on the nuance. Direct translations are rare; natural Japanese often uses mimetic words, verb forms, or descriptive phrases.

Common adverb meaning 'fiercely', 'violently', or 'intensely'. Works for both speed and effort.

Means 'desperately' or 'with all one's might'. Often used when someone is working furiously to meet a deadline or achieve something.

English 'furiously' is often used hyperbolically (e.g., 'furiously happy'). Japanese adverbs like 猛烈に or 激怒して are more literal and may sound odd in such contexts. Instead, use intensifiers like とても or すごく, or rephrase.
When 'furiously' implies anger, use 激怒して or 怒り狂って. When it implies speed or intensity, use 猛烈に or 必死に. Mixing them up can change the meaning.
彼は激怒してタイプした。
He typed furiously (in anger).
彼は猛烈にタイプした。
He typed furiously (very fast).
彼女は激しくうなずいた。
She nodded furiously.
Here 'furiously' means vigorously, not angrily. 激しく (hageshiku) is a good fit.
彼は激怒していた。
He was furiously angry.
Redundant in English but common; in Japanese, 激怒 covers the meaning.
