This ROOT-WORD is the Prefix MACRO which means LARGE & EXCESSIVE development. It is the opposite of the Prefix MICRO, small. This list of words with its abnormalities and manias would be good for writing a science fiction story or opening a circus. There is another zoological oddity I had no room for - MACRObiotus - a strange, bearlike, little animal whose naked body is transparent, andhas globules of fat which look like huge red corpuscles.
