Principal English Translation:
unity, peace, tranquility; or, the opposite, when paired with negation: disharmoniously (see Karttunen)
Frances Karttunen:
CEMĒLLEH disharmoniously (in construction with negation) / falta de union y de paz (C) This appears to have negative polarity. S gives a positive sense of con alegría, tranquilidad for this without negation, but there are no nonnegative constructions attested in the sources for this dictionary.
