A smaller number of nouns in Tamil end in ì -ru (LT alveolar r). All of these nouns change this to ±ì ttu before case, i.e. they undergo gemination. Thus Èì aaru È¢â aattu; `pertaining to the river'; ×´ºì kenaru `well' ×´º¢â kenattu `pertaining to the well'. Other examples are ´¿Õì kayiru `rope', Â¿Õì vayiru `stomach', Ø¶Ôì sooru `cooked rice', and a few others.The LT forms of these words undergo gemination from ì to ±ì, but in ST, the ì forms are phonetically identical with ç, while ±ì merges with ¢â.
