lanku ‘to shine’, vi

l-ar ‘to become pale’ [5496a], Ta. pe
r-u ‘to beget, bear’: pir-a ‘to
be born’, pi
r-avi ‘birth’ [4422] are similarly related, except that Rule 4a applies to them.
Kota, Toda, Iru

la and Ku
rumba dialects (except P¯alu Kurumba) and Ba
.
daga conform
to the rule by showing only e and o before C-a. Kapp (1978) says that P¯alu Ku
rumba
does not show the implementation of i, u [C-a > e, o [C-a, e.g. nila, nilamu ‘ground,
soil’, mu
.
lamu ‘cubit’, ile ‘leaf’. The fact seems to be that this dialect shares with Early
Tamil the dissimilation rule (Rule 4b), i.e. e, o [C-a > i , u [C-a, because of the presence
of such forms as ule ‘fireplace’: Ta. ulai (<

ol-ay < PD

col-ay; see ety. (24)), and puge
‘smoke’: Ta. pukai (< PD
∗
pokai).
2. Tu
.
lu: Rules 4a and b require that all other languages of South Dravidian I and II
have only e, oC-a while Tamil and Malay¯a
.
lam have i, uC-a after the operation of the
r
ule. All Nilgiri dialects which
branched from Pre-Tamil at dif
ferent points in time show
the inherited qualities as expected. So do Ko
.
dagu and Kanna
.
da. Tu
.
lu has two regional
dialects, North (N) and South (S), and two caste dialects, Brahmin (B) and Common
(C). A recent study of Tu
.
lu dialects demonstrates that the NB, SB and SC attest the
inherited qualities (e, oC-a), while the NC has changed these to high vowels (i, uC-a).
This must be a recent dialectal change, which is not related to what happened in Early
Tamil (Rule 4b); e.g. Tu. es-a
.
lu ‘petal’, mo
.
lampu ‘knee’ (SB, SC, NB): is-a
.
lu, mur-ampu
(NC) (Kekunnaya 1994: 42).
3. Kui–Kuvi: it has already been demonstrated (Krishnamurti 1958a: 465) that the
umlaut rule (Rule 4a) preceded the syllable contraction rule (Rule 2) in all South
Dravidian languages; therefore, it is a shared innovation of South Dravidian I and South
Dravidian II. It also preceded the metathesis and vowel-contraction rules of South-
Central Dravidian (South Dravidian II), perhaps going back to over a millennium BCE.
These require us to reconstruct

low) is still an ongoing sound change in Kui–Kuvi–Pengo and Man
.
da (Krishnamurti
1978a). The long mid vowels which resulted from Rule 2 or Rule 6 (metathesis and
vowel contraction) are retained in the other South-Central Dravidian (South Dravidian
II) languages but lowered to -¯a- in Kui–Kuvi (Krishnamurti 1980), e.g.
Rule 4c. Lowering of long mid vowels in Kui–Kuvi
