The Infinitive in tavai has the acute on the first syllable and on the last syllable at one and the same time.,
Thus क꣡र्तवै꣡, ह꣡र्तवै꣡ ॥ This is an exception to 3.1.3 by which त of तवै ought to have got the accent, and it also countermands rule 6.1.158 by which there can be only a single acute in a single word.,
