(I'm not really sure if the title is a correct definition of my problem at all)
I'm not a native English speaker, and I'm used to say:
Spaghetti suddenly can talk
But I've seen a phrase from a native speaker
Spaghetti can suddenly talk
I don't want to rush to conclusions based on one example, so please tell me what's the correct way to say such sentences and how incorrect is the other way (informal or maybe rough error)?
