I learned from a grammar book that past participle denotes either "passive" or "completed" action. But sometimes some past particples seem to have both meanings.
Does this "broken" have both the meanings or only one? It might be it depends. I think the grammatical definition is only for definite cases. A chair could be "broken" by itself(completed) or "broken by someone(passive action)" or "broken by someone(passive) and in the state of it(completed)". What do you think?
