The word "abnormal" comes from the Latin words "ab" meaning "away from" or "not" and "normalis" meaning "according to rule", thus indicating something that deviates from the norm or is irregular.
The term "polychromate" is derived from the Greek words "poly" meaning "many" and "chroma" meaning "color", suggesting something that has many colors.
Therefore, "abnormal polychromate" refers to something that has multiple or diverse colors and is not in accordance with the standard or usual pattern. It is a combination of "abnormal" indicating deviation from the norm and "polychromate" denoting the presence of various colors.
