hi, Iīm from argentina and i need some help to find out if this example of middle voice is ok. " the glass broken", and if this example on ergative verbs is ok. "the cake bake", I really donīt know if they are ok.
I'm not an expert on grammar, but I'll do my best.
You're first example "the glass broken" is very close, but "broken" is an adjective, not a verb form. Correct for the middle voice would be "the glass broke" in which the intransitive form of the verb "to break" appears active but is passive.
Your second example "the cake bake" is slightly more complicated. You are using the transitive form of the verb to bake (I bake a cake, you bake a cake, he bakes a cake etc.) but the context suggests you need the intransitive form (The cake bakes) This is then an ergative verb.
To summarise, correct answers are: -
The glass broke
The cake bakes
In other words, you were very close indeed, but your verb forms let you down!
