Synonymously and literally, Zomi and Mizo are the same, having the etymological root, ‘Zo’. The term Mizo covers all Zo peoples as does Zomi according to their respective users. It is only a matter of pre-fixation and suffixation of ‘MI’, meaning man or people to ‘ZO’. If ‘MI’ is prefixed to Zo, we get Mizo, whereas if it is suffixed, we get ZOMI. According to K. Zawla, Mizo is a poetical form of Zomi. For instance, the accepted poetical expression for a barking deer and a hornbill will be Khisa and Phualva respectively, whereas their accepted non-poetical expressions are Sakhi and Vaphual. However, Zomi is more logical and is the right sequence of syllables, in contrast to Mizo. Because even the people who are more or less familiar with the word Mizo normally accept Zo-fa as the correct grammatical combination of the word when they wish to mean sons of Zoland. They do not say Fa-Zo poetically or literally. If ZOFA is deemed to be correct, Zomi should be deemed to be correct. Moreover, the term Zomi is much older than Mizo. Pu K. Zawla believes that the Zo people had called themselves ‘Zomi’ around the 14th century AD whereas ‘Mizo’ became the official name of the people of Mizoram in 1954 only when the Lushai Hills was changed to ‘Mizo Hills’.
Once Zo is accepted as the generic name of the so-called Kuki-Chin-Lushai people, affixing ‘MI’ to ‘ZO’ either as a prefix or suffix should no longer be a problem. The affix ‘mi’ was considered necessary only due to the earlier misinterpretation of the term ‘Zo’ as hill or highland. As the general population became aware of their progenitor, Zo the people may still be called ZOMI (Zo + People) or Mizo (People + Zo) and their country Zogam/Zoram. Even Mizoram is endearingly referred to as Zoram as in the Mizoram state song….. “Kan Zoram……” (Our Zoland).
In short, imposed names like Kuki, Chin, or Lushai which may have had derogatory origins have no acceptability for common nomenclature among the affected people themselves because they are:
Alien and imposed and not born of the people;
If they have any intelligible meaning at all they incline to be on the abusive, unpalatable and derogatory side;
Only popularly used by outsiders and have not taking root in the social fabric of the tribes themselves, and
There has been a tendency to reserve these terms for a particular tribe or a dialectical group and not for all the tribes as their common name.
