Mandarin - China
Hi, everyone! Here is a sentence, "Its development was as important an event in man's growth as his success in learning how to walk upright." I understand it means that "Its development was an event in man's growth which is as important as his success in learning how to walk upright", but I am quite confused about this sentence's grammatical structure, especially the role of "an event in man's growth" which is placed after an adjective. Any explanation will be appreciated.
