Pāṇini sūtras

The lengthening of the vowel takes place in the case of a stem ending in a vowel, as well as of han and gam, when the Desiderative affix san being jhalâdi (i. e. not taking the augment iṭ) follows.

German In vocalisch auslautenden Wurzeln, sowie in han und gam wird der Vocal verlängert vor dem Desiderativsuffix ‘-sa, wenn dieses nicht das Augment i erhält. (16)
