I have seen a book titled 'retire young, retire rich'
I'm convinced that Hahatse is excellent in English knowledge. In oral English, adjective can be used as adverb. But is it acceptable as correct in written
English as in the above example? Or are 'young' and 'rich' used as complements and 'retire' as linking verb? 'Retire' itself is complete in meaning, isn't it?
Hope to hear from Hahatse or other experts.
