How to identify intransitive verbs

I have an advice: try to add "something" or "something good" as a kind of object after them.

it should sound good for transitive, but somehow "weird" for intransitive verbs:

Transitive:

I ate something
I like something

Intransitive

*I sleep something
*I cry something

this is a way of saying: intransitive verbs can't take an object, while transitive can ! (this this the definition of the difference between them actually)

The details that best show evidence of tribal traditions are, "never in the history of his people had a man married a woman who spoke a different tongue” and "it has never been heard," was the verdict of an old man speaking a few weeks later.
