She doesn’t dare to leave the baby alone.
Is dare in this sentence transitive or intransitive?
Added by javalatte from comments posted below, because the OP does seem to have hit upon a confusing situation:
The British English definition in the Cambridge Dictionary seems to suggest that it's an intransitive verb, whereas the American English definition in the same place seems to suggest that it's transitive.
The entry in Merriam-Webster doesn't seem to shed any light on this at all.
