How to spot an intransitive verb?

Grammarian-botHow can i easily differentiate between a transitive and an intransitive verb? Are there any set of rule that set them apart or is it solely based upon the context of the sentence?

A transitive verb has a direct object. Without examples, it is difficult to explain the difference.

There are transitive verbs, intransitive ones, and there are verbs that are of both types.

I fell off the three. The highlighted part is an ad

<I fell off the three. The highlighted part is an advebial phrase, 'off' is the adverbial particle. "fall" here takes no object.>

Would "three" be a typo there?

I started learning English from scratch, without any previous knowledge, three years ago.
I have never met any English teacher, only books and net.

I'm not on your back. I was interested in knowing how you pronounce the word "tree". Many of my Spanish speaking students pronounce it as "three" in English. Often, they spell it that way too.
