There were earlier messages on Nahali. I deeply appreciate the
insightful comments of Piotr. Here is an elaboration which proceeds
on the assumption that Nahali is an Indo-Aryan dialect and provides
an outline of Me-lah-ha dialect, c. 4th to 3rd millennia BCE.

Mleccha, Milakkha or Me-lah-ha: maritime people and their language
The argument is that mleccha connoted the parole of a proto-Indo-
Aryan language and that mleccha speakers were the dominant
population Bha_ratam janam --, from the days of the R.gveda,
variously referred to as da_sa, dasyu, vra_tya or asura all terms
used as behavioral traits as were the terms, a_rya or deva,
connotations of 'excellence' or 'righteous behaviour'. There is not
an iota of evidence, in early periods of the civilization of
Bha_ratavars.a, to treat these terms as ethnic identities.
Art, cultural texts, epigraphs, archaeological discoveries, notes on
early shell- and metallurgical- techniques and economic texts are
used to substantiate this argument.
A surprise result emerges: a key to decode epigraphs using rebus
method and proto-phonetic variants (substratum) of present-day
languages of the Sarasvati Civilization area, relating epigraphs to
the professions of lapidaries and smiths: shell-/stone-/mineral-
/metal-workers.
The indigenously evolved civilization matured in an extensive area
from Ropar to Lothal along the banks of River Sarasvati and the
cultural heritage lives on in Bha_rata, thanks to the contributions
made by mleccha (me-lah-ha), contributions exemplified by samudra
manthanam (churning of the ocean), as a co-operative endeavour among
bha_ratam janam.
