Translation guide
The English adverb 'abruptly' describes an action or change that happens suddenly, unexpectedly, and often without warning or smooth transition. In Japanese, there is no single direct equivalent; instead, various adverbs, verb forms, and descriptive phrases are used depending on the nuance—whether it's a sudden stop, an unexpected change, a blunt manner of speaking, or a sharp physical movement.

突然 (totsuzen) is the most neutral and can be used in both formal and informal contexts. 急に (kyuu ni) is very common in everyday speech and emphasizes the speed of the change. いきなり (ikinari) stresses the lack of warning and can carry a negative nuance of rudeness or surprise. For formal writing, 突然 is safest; for casual conversation, 急に is often more natural.

It got cold all of a sudden, huh? (casual)
I don't know what to do if you say something like that out of the blue.
When describing someone speaking abruptly (rudely), English often uses 'abruptly' as an adverb. In Japanese, it's more natural to use adjectives like ぶっきらぼう or 素っ気ない in their adverbial forms, or to describe the manner with phrases. Simply using 突然 for speech can sound like the person started speaking unexpectedly, not that they were curt.

He abruptly cut off his words and left the room.
