>Is there some correspondeces not explained in Greek between "regular" IE forms like taphos and "irregular" tymbos (<*dmbHo-<*dHmbHo-); thauma/taphos/ thambos/tho: ma. …
I’m still not clear what you are saying.
There are two distinct roots (according to Pokorny): *dhabh and *dhembh
The first gives taphos = “amazement”
The second gives taphos = “grave”.
Both show regular processes.
Tymbos = “mound” is from *tewh2, with an –m extension (quite common) The development is regular.
