An adverb appearing as ᴱQ. rísimande “passim” (as noted by the editors, this is Latin for “scatteredly, here and there, at random, anywhere, everywhere”) in the Qenya Lexicon of the 1910s as an elaboration of ᴱQ. rísima “scattered, ubiquitous, universal” under the early root ᴱ√RIẎI (QL/80).

Neo-Quenya: Since there is evidence the root ᴹ√RĪI̯ survived into the early 1930s (PE21/38), I retain ᴺQ. rísimandë “passim [Latin]; *scatteredly, here and there, at random” for purposes of Neo-Quenya. I would assume the s was originally þ to explain the retention of intervocalic s.
