See these examples.
1-The boy breaks his toys every day (active form).
2-his toys are broken every day by him (passive form).
But we also use "broken" as an adjective to express the current state of something that is in pieces because of being dropped.
For example,
3-his toys are broken (the current state of his toys)
So, what is the difference between "broken" in 2 and 3?
I would say the 2 focuses on the action and the 3 focuses on the state.
My question is that
Can any V3 form of a verb be used as both one for action and one for state like the verb "break"?
I feel like some verbs can be used that way, but not all.
For example, Say I have some colored clay I bought from the Toy supermarket.
I shape the clay every day (action)
The clay is shaped by me every day (action)
The clay is shaped like an egg (state)
I am not sure if "wash" can be used that way.
I wash my shirt every day (action)
My shirt is washed by me every day (action)
However,
Can I say "My shirt is washed" to express the current state of the shirt?
Can I say "the cake is eaten" to express the current state of the cake?
Can I say "the bird is flown" to express the current state of the bird?
If not all V3 form of a verb can be used as an adjective, what kinds of verbs can be used that way?
