Hi,

Is there any difference between the adverbs ‘instantly’ and ‘instantaneously’?

Many thanks,

Unless you’re talking about physics, there’s no real difference. In fact, my dictionary uses the word “instantly” to define “instantaneous”.

Which one is a native speaker more likely to use?

Thanks,

Tom

Hi Tom

I’d say “He died instantly”.
Using instantaneously there would sound a little unusual to me.

Instantaneous sounds better to me in your second set of sentences.

the 2nd #2 is incorrect. his death was instantaneously should be his death was instantaneous.

Good point, Tomb.
