v2.c12.188

Only two of these words take the long -*â*, and of these तांबा may be derived from the Sanskrit form ताम्रक, which would lose the क, and the two vowels would coalesce into a long vowel, as will be shown hereafter. सूद्रा was probably regarded as an adjective. अंबा in M. is fem., the change of gender accounts for the long vowel.
