Pāṇini sūtras

Of such a doubled sound-imitation word, to which the affix ā is added which causes the elision of the fiual at, for the final t of the first member and the initial consonaut of the second member, such subsequent consonant is always the single substitute.

German Folgt auf eine solche verdoppelte Schallnachahmung das Suffix ā, welches den Abfall des letzten at bewirkt, so wird für das auslautende t des ersten Theils und für den anlautenden Consonanten des zweiten Theils dieser letztere allein substituirt. (100)
