Dear all,

Many thanks to everyone who replied on- and off-list!

In addition to your suggestions, I have also been looking at the section 'Transfer of present classes' in Oberlies' Grammar of Epic Sanskrit (2003: 189-202), and Lanman's On multiple presets and on transfers of conjugation in the Sanskrit verb system (JAOS 13 (1889) XXXVI-XXXIX). It is interesting that secondary -aya-formations are often excluded from such considerations, probably because they are automatically assumed to be causatives rather than alternative (simple) present-tense forms.

Thank you again, and I hope you all have a very good week ahead,

Dear all,

Is there an overview or systematic study of Sanskrit verbal roots either changing what present-tense stem class they belong to, or moving towards belonging to more than one class? (I am particularly looking for verbs moving into/also taking on forms of Class X, but am also wondering about movement towards thematic formations more generally. So far, my searches haven't had any useful results.)

I was going to go through Whitney to make a list of my own; but before doing that, I thought I'd check whether the kalpataru might have a piece of fruit all ready for me.

Many thanks,
