I am quite new to the idea or postpositive adjectives, and would like to know if the adjective 'alone'(which is usually predicative) can be placed in that position.
- I alone cannot change this world.
- I alone can handle this.
- He alone will save us all.
Or perhaps the examples I gave are grammatically incorrect?
If that is the case is 'alone' a predicative-only adjective/adverb?
Do I need to separate it with commas? Ie. I, alone, cannot change this world.
