Help Transitive and Intransitive

[miitutu]

1. Does all tadoshi verbs has a jidoushi verb to pair with?


2. How do you differentiate volitional and non volitional form verbs? Do we categorise them like how we do for jidoshi (intransitive form) eg. Action performed without an object



3. Are all jidoshi verbs, potential form?

I don't know the answer to your 2nd question. You mean like 書く vs 書こう?
Isn't it the same as in English, where the difference would be

I am writing
vs.
I will write something?

I think the answer to your 3rd question is "no". For example 実る by itself isn't a potential form. That would be 実られる.

1)
As the site Majestic-san provided shows, no.

2)
As mentioned in the site, the most common definition of tadōshi/transitive verb is "verbs that take を as the object marker".
Notice that not all verbs that have an object are transitive verb. For instance, お金が要る means "I need money", thus, お金 is actually the object in meaning, but 要る is an intransitive verbs because が is used to indicate the object.

Similarly, some action verbs that take を are intransitive verbs. を indicates the location of movement in the following verbs.
e.g.
廊下を歩く
道路を走る
坂道を登る
橋を渡る
空を飛ぶ

Also, を indicates the departure point of movement in some intransitive verbs.
e.g.
故郷を離れる
家を出る
大学を出る

These exceptions are not so many, so you can think that verbs that are used with を are usually transitive verbs.
