(b) Thirty-six consonants, viz.: Five series of stops and nasals: guttural: k, k/i, g, gh, it; palatal: c, ch, j, jh, ii; cerebral: t, th, d, dh, 71,- dental: t, th, d, dh, n; labial: p, ph, b, bh, m. Four semi-vowels: y, r, 1, v. Three sibilants : palatal ,f, cerebral ..s, dental 5. Two aspirates: voiced h, unvoiced h (visarga). A nasal with loose closure of the lips M (anusvara), and another nasal 4c (anundsika) which probably was a simple nasalization of the vowel rather than a consonant proper.
Consonants.—The consonant-system has remained much truer to the original Indo-European. It is characterized by the rarity of spirants and by the opposition of unaspirated and aspirated stops (both surd and voiced) in each series. In preserving the voiced
aspirate stops unchanged, Sanskrit and its descendants (for most of the modern Indo-Aryan languages still possess these sounds) are unique among the Indo-European languages, in which these sounds either became surd aspirates and later spirants (as in Greek and Latin) or lost their aspiration (as in Iranian, Balto Slavonic, Armenian, Albanian, Germanic, Celtic). Thus to Greek phgro, Latin fero, Eng. bear, Sanskrit corresponds with bhdrdmi, to Gk. gtheke, Lat. fecit, Eng. deed with cidhat.
Some consonants were restricted in their use : ii appeared only before or after palatals, it only finally or before gutturals (and where a guttural had subsequently disappeared), to only between vowels and semi-vowels or before cerebral stops, h only finally or before sibilants and surd gutturals or labials, in only finally or before consonants. Neither aspirate nor h nor s ended a word. At the end of a sentence only the following consonants were used: k, t, t, p, n, n, m, Of the palatals ch appears as a single consonant only initially: elsewhere it is always doubled unless preceded by another con sonant, for it corresponds to the Indo-European group e.g., chinrldnti "they cut"=Latin scindunt, gdcchami "I go"=Greek bcisko, vaiichd "wish" = Germ. Wunsch. j represents two I.E. sounds (1 ) palatal (=Gk. g, Avestic z) : janah "birth"=Av, zanO, Gk. genos, Lat. genus; (2) velar gw before an original é or I (=Av. j) : jivdla "alive"=Av. jivo, Lat. vivos, cf. Gk. bios, Eng. quick. jh does not belong to the Indo-European part of the voca bulary, but appears only in onomatopoeic and borrowed words, or in words taken from the vernacular in which the frequent Sans krit groups dhy and lay became (j)jh.
Of the sibilants .§ corresponds to I.E. palatal in this Sanskrit agrees with the other eastern I.E. languages (Balto-Slavonic, Albanian, Armenian, Iranian) which have an s or sh sound as opposed to the k (h in Germanic) of the western languages: e.g., Seam "ioo"=Av. satem, Lithuanian .i'inttas, but Gk. he-katon, Lat. centum, Eng. hundred. Before the surd dentals this s be came s: vikiti "enters," vistcilz "entered." But s also corresponds to I.E. s when preceded by i, u, r or k, agreeing in this with Iranian and partly with Armenian and Balto-Slavonic.
