To repeat myself, root "constraints" are only tendencies, not rigid
inviolable rules.
There are 9 fairly certain roots of the form DeD in PIE:
*bed to swell Pokorny p96
*bend tip Pokorny p96
*de:g to grasp Pokorny p183
*g'eid to suck Pokorny p356
*geid to stab Pokorny p356
*geig' to stab Pokorny p356
*gleg soft Pokorny p 401
*gred to sratch Pokorny p 405
*gWreig' to sleep Pokorny p485
