vowels other than a/ā when, as a rule, it is not word-final and not followed by r. From this unique
environment arises the name ‘RUKI’ and a number of studies have been dedicated to the 
interpretation of the environment, which apparently does not form a natural class, a number of 
exceptions, and variability. 
 This paper tackles the problem of the interpretation and implications of the unique 
conditioning factors of the Sanskrit RUKI rule and claims that RUKI is partial place assimilation
with multiple origins. While all the four triggers are behind dental in place, they are phonetically
heterogeneous, i.e. vowels and consonants that in turn consists of an obstruent and a sonorant
with varying distances from the dental. They also show distinct phonological behaviors: while r
and u are common retroflexion triggers, i often triggers palatalization and deretroflexion, and k
is not known as a retroflexion trigger. A careful examination of Ṙ gveda shows further that
irregularities and phrase-level application depend on whether the triggers are vowels or
consonants. These phonetic and phonological differences, together with comparative evidence, 
suggest that RUKI originally consisted of a series of retraction processes, whose outcomes
eventually merged as a retroflex sibilant in Sanskrit. The nature of the triggers has implications
on how the process as a whole arose and developed.},
