rohati

for the Sk. rohati of ruh to grow we find the regular P. correspondent rūhati: see rūhati1. The Caus. of this verb is ropeti (to make grow): see ropeti. Another root, restricted to the Pāli, is seen in rūhati2 (with pp. rūḷha) and is equal to rundh (rudh rumbh) to break. The Caus. of this root (ropeti2) is either an indirect formation from it or (more likely) a direct representative of rup = lup as in P lumpati. To the latter belong the prep. compounds oropeti & voropeti.
