I believe in English you can say "no" when something unfortunate is about to
happen or has already started — suppose somebody has just bumped into a table
with an antique vase and now you see it swaying on the verge of falling to the
ground. Aside from rushing to prop it up, you can call out "no!" or "no, no,
no!", and I think it would be a bit different from a dismayed "no" said after
the fact, for example, as the first sounds to me almost like an effort to
convince something or someone (the universe? the falling vase?) to stop the
accident from happening while there is still a chance to do so. It works
similarly in my native language (my calling out "no!" the moment something
slipped out of my hands, but didn't reach the ground just yet, was actually
what prompted this question).

In Japanese, however, there isn't really such a versatile "no"-word as in
English that one could assume would work in this situation. The question is,
then: how do you express this sentiment in Japanese? What exclamation would be
used in a similar setting?

question
words expressions
How to express this kind of "no"?
In my experience the word **やだ** or more informal versions of いいえ such as
**いや** are used in response to sudden negative events.

answer
For something bad but spontaneous, I feel いけない is a better match.

Naturally if there’s a sense of impending danger or of warning others, you may
also consider あぶない as an interjection.
